I’m concerned that people are already eager to bury the fediverse and unwilling to consider what would be lost. The solutions I keep hearing in this space all seem to hinge on making the place less equal, more of a broadcast medium, and less accessible to unconnected individuals and small groups.
How does an instance get into one of these archipelagos if they use allowlists?
Same thing with reply policies. I can see the reason why people want them, but a major advantage on the fedi is the sense that there is little difference between posters. I think a lot of this would just recreate structures of power and influence, just without doing so formally–after all the nature of scale-free networks is large inequality.
Not so concerned on that–people being able to establish their tolerances for whom they want to talk to is fine with me. But if the system goes towards allowlists, it becomes more cliquish and finding a way in is more difficult. It would tend towards centralisation just because of the popularity of certain posters/instances and how scale-free networks behave when they’re not handled another way.
I run my instance and that’s definitely not my experience. Which is of course not to say it can’t be someone else’s. But something, in my opinion not unimportant, is lost when it becomes harder to find a way in.
