One of the things that the Stack Overflow brouhaha demonstrates is that it doesn’t matter if a service was founded by people trusted by the community (Atwood and Spolsky) and was broadly community-led. If it’s a VC-funded startup, they will sell out their users at some point.
@baldur Trust is all fine, but what counts is the license. In this case, our content is under CC-BY-SA. What seems relevant to me:
- using the content for AI training does (unfortunately?) not trigger the attribution requirement ("fair use", bla bla)
- it should be feasible to pull of a fork of Stack overflow, with a legal copy of all existing content
