At the end of the day users have to police their instances by leaving if the policies are too draconian for them. Casual users on a big enough instance might not care too much at first, but I think there would be a slow but ever-increasing migration off-instance.

It really depends on how many users disagree with the policy. My last instance defederated Threads and I didn’t agree but didn’t care enough to leave. It was database issues that lingered for months that made me leave and I don’t know my current server’s policy on Threads.

Is there a genuine question there? That sounds like a feature rather than a bug. If you don’t like it, move to another instance or make your own.
