I don't like the "they haven't done anything bad yet" argument for staying federated, since there are much better reasons for not doing so. They either have already, and we aren't talking about it yet (ex. downranking fediverse content, those closed door meetings with admins), or they are going to once they need to extract a profit.

I wouldn’t be surprised if they’re already scraping data from every other instance that federates with them.

I would be surprised if they aren't already, and they're likely scraping data from the defederated instances as well.

I think microblog instances should stay federated because that's the best way to fight against threads. (longer discussion here: https://lemmy.ca/post/11771031)
