I happen to fall into the center of that venn diagram and honestly I feel like the “preemptively defederate!” crowd is acting before it’s even truly clear how to best act and everyone else who says “ehh let’s wait and see how this is going to go before we act” is just getting drowned out by the folks screaming about the end of the Fediverse.
I don’t trust Meta any further than I can throw their servers, but I find it hard to imagine there won’t be some middle ground that isn’t “BLOCK EVERYONE WHO SO MUCH AS TOUCHED A META PRODUCT ONCE” that ends up being the healthiest option

Obviously as an individual I also have the benefit of being able to just go with the flow that an instance admin might not but still
