The point we’re trying to make is this should be OptIn BECAUSE it’s created by a private entity, that’s all. It’s not an outrageous take.
Out of the over 46,000 independently operated servers on the fediverse, how many are run by private entities? I don't know but I am guessing that it is more than 1.

At least with Bluesky and Threads, it is easy to block. But I am guessing that it would be nearly impossible to figure out which of the 46,000 ActivityPub-enabled servers are commercial and which are not.

And Threads will be connecting to ActivityPub natively. And so will WordPress. Both will bring in millions of users.

I respect people's choice to block whomever they want, but the ActivityPub part of the fediverse already has commercial servers in it. Bluesky would just be one more, which you are free to block.
