I genuinely don't understand what you're talking about. Should I not correct people when they say factually inaccurate things about a service I care about? Should I not point out that their use of a service is not aligned with the intended use of that service, or that a community already exists with differently aligned goals? Should I not point out that they are not in a position to override that community's purpose and vision?

Because I absolutely will not agree that other people should get to change what Stack Overflow is, simply because they think it should work like the other sites it was explicitly intended to provide an alternative to.

I'm trying my hardest here to be courteous and to consider all sides: the fact that the software doesn't work optimally for our goals; the fact that the site owners have unaligned interests (corporate ones around ad revenue and site traffic); the fact that key parts of the site software were poorly designed at the start and not properly re-evaluated and fixed (in particular, the reputation system, which saw only a passing attempt to invite meta-discussion and then no corresponding change); the fact that the site's UI affords misuse by looking too much like a discussion forum (compare and contrast Wikipedia: there's no sense that anyone is replying to anyone else except on the Talk and other meta pages, and the edit form is hidden behind a link).

For what it's worth, alternatives exist, and I prefer them. In particular, I use Codidact (https://www.codidact.com) and I consider that its design has fixed many problems with the Stack Exchange network. But fundamentally, these kinds of Q&A sites are meant to work a certain way in the main Q&A space (although Codidact opens up the possibility of parallel related spaces, not just meta). They are fundamentally and crucially not a place to just ask something because it's on your mind (or with the specific intent of getting out of a bind), without heed to existing questions, and hope that someone addresses you personally. That's how traditional forums work, and ultimately the cause of all the things that made experts fed up with them and motivated to try something new in 2008.

I've written a lot ITT because there are a lot of misconceptions about Stack Overflow out there, and many of them are quite popular; and because the site itself is not very good at presenting the needed correct information.
