I agree and I personally think the whole preemptive Threads ban is stupid in general, but at least one major bridge has had to be turned off because people on the Mastodon/ActivityPub side of things got angry. I don’t mean the people behind ActivityPub of course, I’m sure they were chuffed their protocol got buy-in from a major player.
If anything, large corporations using open standards is better, even in situations like Google Talk where Facebook and Google dominated the protocol for a while; at least the protocol is useful for regular people.
The problems that plagues Mastodon at the time have all been fixed as far as I know, but it’s too late now. Other, more difficult problems remain, like the inconsistencies between server on how many likes/comments a post has and the inevitable perception that you need to create an account on every server to follow people because the follow button doesn’t work by itself even if you’re logged into your account in another tab.
People don’t join a social media platform to go on an adventure and see what every button does. They came looking for a new Twitter rather than a new experience and Mastodon, and kind of still is, a bad Twitter. It’s a great Mastodon, but that’s just not what most people were after.
