some users will just get fed up with the demands/changes they’re making and move to an instance that is incompatible/defederated with Threads

But many users might now and then we've given Threads leverage - stay federated with Threads and give in to their demands and changes, or lose a big chunk of your users. That's not leverage I want Meta to have. So I say defederate ahead of time.

I’m strongly against people pushing their values onto others. I would much rather have individual users block that instance if they so wish instead of someone deciding for them.

I've seen this sentiment before and I understand how it can seem appealing. Why should anyone decide what any user sees? Just let every user decide for themselves.

However, there's multiple problems with that idea. Firstly, it doesn't scale. It's not sustainable to have every user block all the bad stuff for themselves before they get a sane feed. Secondly, it's not a whole solution. A single user can block an instance, but that instance will still have an influence with votes (and blocking an instance right now in Lemmy is only blocking community posts so you'll also see comments from an instance you "blocked" and this is by design). So user blocking simply doesn't do the same thing as defederation does.

Also nobody is pushing values onto others really - each user decides for themselves what instance to join. They can join one endorsed by the Fedigarden og fedipact or whatever else they want. Or they can join another one. Up to them.
