It is correct to be "hostile, aggressive and hard to work with" when you are inundated with requests from others to "work with" you on something that is radically different from what you are trying to accomplish.

I will not look inward because I am objectively doing nothing morally wrong here. It's fine if people think I'm "hostile" because I politely tell them what they aren't supposed to do while they think they should be entitled to do it anyway, because them doing it actively harms things I actually care about.

I disagree with the choice of "aggressive", though. This is a purely defensive posture.

Stack Overflow has a community which is trying to create something useful and is not trying to cause harm to anyone. As such, that community is entitled to have and pursue goals that aren't aligned with those of others, and should not be expected to change those goals simply because other people don't share them, or because they want to use Stack Overflow's time, space and other resources to do something different.

That community is a separate entity from the company (Stack Exchange, Inc.). The community owes nothing to the company, as it has been paid nothing, and is exploited to drive traffic and ad revenue while their content feeds AI.
