There's a few items that could be considered gamebreaking only if a GM was incapable of making a decision, since these things aren't 'it's missing and we haven't got a clue', but more 'it's missing and there's like two options'. So yes, there's flaws, but I don't think 'I'm not sure if this rulecall will remain correct in the future' can be considered gamebreaking. It'd be different if there was a gap so big no judgment call could be made whatsoever.
As for what that errata document 'missed', that is a misrepresentation of what that errata document was: A HOTFIX meant to address straight-up rule contradictions. Already then the list of known items was bigger, but it was a matter of priority. As such, 'missed' is a label not matching the actual situation. 'Prioritised to make sure the game is playable on launch', where a handful of items didn't get covered, is a more accurate description of what that errata was. To claim the hotfix team, errata team and demo agents, which all worked hard on putting together a list, just missed 250+ items, is far from nice towards them. If you want to know something that actually get missed, 'you die at 0 Essence' is probably one so there are in fact things we all missed back then, but I bet you that approximately 99% of those 250+ items were in fact already covered and are currently being reviewed fix-wise, if they're in fact something needing fixing.
Now I agree that I would like transparancy from JM Hardy on the current state and intent of the errata process, since a far greater list than the Hotfix is currently in a review state. But claiming the Reddit community, where a moderator deliberately leaked a PDF code despite their anti-piracy rule (which Reddit members upvoted and commented on, yet nobody spoke out against) and where the moderators explicitly refused to act on any anti-piracy requests, forcing DMCA requests instead, is right about things? Yeah no. They don't deserve being defended.
Plus none of that changes that apparently they lie about the hotfix errata not being present in the PDF. That in itself shows just how reliable their mob mentality is: To actively advocate, promote and defend fake news, while they make sure to bash SR6 wherever they can in an attempt (as several people have in fact explicitly admitted) to ruin SR6 so that CGL will drop the franchise, is not something anyone considering themselves a fan or a decent human would engage in. I am far from surprised that the people who chose to severely violate their NDAs are primarily active on Reddit. It's a shame that they chose toxicity, but given that they made that choice willingly, I'm just going to consider them part of the toxic past and I will look at the future instead.
Which reminds me, I still have a few statblocks to write and a dozen archetypes to make legal printouts of with HLO. And I need to rewrite a few legwork blocks. See you around, y'all.
