I disagree with pretty much all of that.
The reason is: actions like eating, pooping, and pulling cloth over the optical sensors of some device are all physical actions that take place in a physical world that is modelled on the real and objective world. We can fairly make assumptions that because something is true and/or possible in the real world, it is therefore also true and/or possible in the fantasy world modeled on the real world.
That's true until it isn't. For example, I have a cyberarm that has +4 strength compared to my meatbod. I try to pick up something heavy, or pull myself up the side of a building, or break a door down. To what extent does my arm help me?
I am sitting at a table with my arms resting on the tabletop. My gun is in my holster. Someone is staring me down with a gun pointed right at me. In the real world, there's no way I can clear my gun from the holster and take a shot before I get shot myself. But in Shadowrun, I have wired reflexes, and my opponent does not. To what extent do my synthetic nerves give me an opportunity to outdraw them?
There's all sorts of ways that Shadowrun's physical situations get away from our real world and require judgment calls that are not, can not, be based on our experiences. It wouldn't be a very good fantasy game if that weren't true.
The examples you give may not be translatable in a 1:1 ratio to real life experiences, but they're still
rooted in real life. Having one arm massively stronger than the rest of your body, or having impossibly quick reflexes are situations that we CAN imagine and extrapolate upon if necessary when the rules don't address something.
Contrast this to the situation you mentioned: trying to hijack someone's matrix persona by (per your example) subduing them and forcibly making them log in to the matrix but then controlling what they do somehow via control of the commlink. I told you not only is there no matrix action that covers this or even anything categorically LIKE this. This is unlike the scenarios just listed above in that we're not even beginning our hypothetical context in a real world analogue. We have the Matrix rules. We have SOME fluff, but not very much this early in an edition. Hell, the "brainwave technobabble" may or may not even be correct anymore as that's from a prior edition. Things get retconned. Things get outright changed (Crash 2.0...). Until there's some indication that what you're suggesting is even possible, it's not a fair assumption to say that just because it can be imagined then it must be possible.
EDIT: that concluded a little more harshly than I intended. As I said upthread, if you want to
house rule doing such a thing, great! It's just not a concept that's allowed for under the
published rules.
Shadowrun's two other worlds, Astral and Matrix, do NOT have this working in their favor.
And thus it is the job of the authors to create in all our minds a shared understanding that is internally coherent enough to give us the ability to reason about it intuitively.
Is that easy? No. But it's important.
And it's funny because you bring up magic. Shadowrun's magic system has been praised for thirty years because actually, it does exactly this -- establish a base of ground rules from which you can intuit behaviours that feel natural. This is not an impossible problem.
And yet, if someone came up with some concept that was impossible under either the rules AND the fluff of this and prior editions, you wouldn't argue that it should still be possible, would you?
For example: A player familiar with D&D wants to create a perfect translation of a Ring of Three Wishes for Shadowrun. There are concepts here that just flatly are not allowed for under the lore and the rules. Even if you were to try, it runs up into all kinds of mechanical problems (how does a mundane even activate the ring? how are the effects of the "wish" sustained? etc etc) Sometimes what you want to do is just outside the scope of the rules. (looking at you, "hijacking someone else's Matrix Persona")
The Matrix is not the TCP/IP protocol network we call the Internet. Hell, one might even infer from the Noise rules that the Matrix doesn't even comply with physics. One CANNOT imply that just because something is true about the Internet, it must therefore also be true about the Matrix. That parallel simply is no longer true in the way it is for the physical world(s).
This is a total cop-out as well as a straw man argument. The Matrix doesn't need to resemble real-life computers, nor have I said anything like that. It just needs to make sense on its own terms, like Shadowrun's magic system does. And to do that, the in-game fiction has to align with the game mechanics. If something is mechanically impossible -- particularly something players are naturally going to want to do - that should be impossible in the fiction too.
I'd be careful wishing the Matrix were as coherent as the magic realm.... I'd say the better state is the reverse

For example: 6e forgot to say you can't just snipe people from astral space with manabolts. Obviously it's IMPLIED you can't since it's always been that way (even in the bad old days of bridging through an active focus), but they forgot to say it. So is 6e doing away with that age old rule? RAW, it's impossible to say thus far... even if the intent is "obvious".
Anyway, moving on:
So in the case of the Matrix, you don't get to color outside the lines. (Ditto for the Astral).
Then what would you say you are doing here:That being said, the question of physical spells and astral projection is a thorny one. One one hand, the spell only has to modify your brain, because your brain generates the mind/aura. On the other hand, the aura can't be touched by physical spells after it leaves the body and therefore it can't benefit from increase attribute.
RAW says nothing (that I am aware of) to address this issue directly. But what you did here was: you started with what RAW does say, and extended it to consider the problem. Now, you don't have a concrete answer. But you do have the basis to make a ruling, to explain that ruling to the rest of your table, and everyone nod and say "makes sense, cool."
Your own posting history has many more examples of this sort of thing. I could post quotes here all day.
Ok so let's deconstruct that.
You're referring to a post I made in another thread entirely. For context, that thread (or that tangent of that thread, as the case may have been...) is about the ambiguity IN THE MAGIC SYSTEM regarding whether physical spells can continue to affect an astrally projecting character, and if so, does the spell only affect the empty body or somehow "go with" the astral aura.
While the magic rules are full of holes, it does still say that Physical Spells only affect the Physical realm (pg. 131).
Ergo you cannot benefit from the spell AFTER you've begun projecting. However, if you're NOT projecting, you're in the physical realm (if you're a metahuman, which is the assumption here) and can therefore be affected by, say, an Increase Logic spell. So what happens if you subsequently project? You can't point to the
relationship of the mind to the physical body for any number of reasons. Of course foremost among them, and perhaps ironically this is exactly relevant to the conversation at hand rather than being an example of a case of inconsistency on my part, is that the rules simply don't establish that the pineal gland links your aura to your physical body.
So again, we're seeing a case of "toss out the 'real world', and go by what the rules say and don't say". Unfortunately in this case, the rules fail to adequately cover so the official answer is "GM decides." Of course that's not a suitable answer for SRM where you have multiple GMs, so SRM has a "for SRM purposes" answer for that particular issue.
All I want is for the matrix to make as much sense as the magic system does...
Between you and me: You make one of us
