It's not a contest. But good to know that if it were, I'd be winning. Just kidding. Really.
Nah, credit where it's due

I can handle losing a few battles...
Trust me, my players make plenty of mistakes on their own that allow me to demonstrate that the world is a scary place. To throw something at them arbitrarily, just to prove I'm the boss of them makes me a crappy boss.
I completely concur on this point, but every now and then, even arbitrarily, things go wrong for shadowrunners.
Sometimes, someone just decides '
Tag, you're it', and the Matrix dragon is a prime example.
A few sessions ago, I had to remotely self-destruct a ¥26k commlink because it got left at the scene. That was two run's pay gone due to just damned bad luck, but it was the price of the industry.
Every now and then, it's constructive for runners to realise that they are the little fish. While they may be the cinematic heroes of the movie, they are the Running Men in a much larger game.
What I cannot understand is how any runner, anywhere, can maintain any decent rep without anyone ever knowing how to find them.
1) You can't live completely off-grid, or you'll never get any work
2) You can't ignore all your chummers, or you'll never have anyone to work with
3) You can't change commlinks every day, because your fixer needs to know how to find you
4) You can probably change physical safehouses a lot, but you have to either keep them in multiple fakeID names, or trust in Squatting at non-descript, unlisted locations (or a combination of the two).
Even the most paranoid runner, if they're active still in the biz (ie not Retired) leaves a data trail (physical, matrix or both).
Rarely, but possibly, someone large may spend their resources at hand to follow that trail, if they feel it's worth the effort.
In the case of this Matrix dragon run, all it's doing is providing two physical hard-drives either at the meet (which I think was Virtual only) or at one of the group's FakeID locations (I don't believe it says it has to be the runner's prime/active location, just has to be delivered to a valid address).
All I'm saying is that this hardly necessitates the group shutting shop, killing the courier and passerby, then moving to an Antarctica ward to watch the penguins
Note: Those penguins could be spies too!
That shift walk they do looks pretty suspicious to me 
Actually, what it's supposed to do is prove outright to the PC's that this is a Johnson not to be messed with. It's the equivalent of being interviewed for a secret job and the prospective employer mentions: 'Oh, we have your drivers' license and social security number already, no need to fill that in.'
Jup and now give me the reason why that motherfucker needs runners. If I dont believe it, players dont believe it either. And it would ruin the game. Talking about the fun. Game.
*shrugs* There's a bunch of reasons why runners are needed day-to-day, all of which still apply here. How about:
1) I have no physical form to do the job myself
2) I've got an opportunity to hack an Aesir satellite ATM, which is going to take me a few days. BRB kthxbye
3) I can't take the chance someone will see me
4) I'm testing you for something bigger
5) You're expendable in case things get dicey
6) You're deniable in case evidence is left at the scene
or further secret reasons options 7) through 100)
What, you don't think the CEO of DocWagon keeps a file on which of his clients who come in regularly with bulletwounds?
'
Hmmm,' he says.
'I need some deniable assets for a job. I wonder if they'll be interested in doing some work for me in return for a Platinum contract upgrade?'
