IF (and it's definitely an "IF") this is an intentional and permanent change by SE management, they are fundamentally changing the basic understanding between users and SE, and they have to understand that some subset of users are likely to quit using SE in response. Again, it's hard to say how many. Maybe enough to have a material impact, or maybe not. That would be the gamble they'd be taking though.
Given the way they've communicated in the last 2 weeks or so, this seems pretty clear. Before we had employees engaging as real human beings all over the place, and you were talking to Jon, Tim, Robert, Shog, etc. and not "Mr. Ericson, title such-and-such, representing Stack Exchange Inc."
Now all we have is a bunch of announcements, with no discussion, engagement, or even a recognition that anything is even being read. It feels like pissing in the wind – disagreement is one thing, reasonable people can disagree, but ignoring is so much worse; it's like you're not even taken serious.
Stack Exchange has gone through various phases (e.g. the "Jeff era" was different from the "stagnation era" that followed after he left), but the implied social contract was always that the community would offer their spare time and in return they would get a platform and some voice in how that platform is run. There have certainly been moments of friction in this relationship, but the basics of it never changed until now (not even with the whole debacle surrounding the firing of a moderator a few years back).
I certainly didn’t sweat it out helping people on SO to pay for Sam Altman’s fucking swimming pool.
Generative AI doesn't follow copyright or even explicit software licenses as we have seen in AI art with human signatures and Microsoft Copilot.
Sam Altman is still chairman of the board of directors of Y Combinator.
