Oddly, this may well be what really spurs on decentralisation. I suspect more and more individuals, or small groups, will spin up their own instances rather than all gravitating to the bigger ones, due to issues like this.

Because, ultimately, the more tech-savvy users (the ones more likely to be into the Fediverse, anyway) will want to decide for themselves what content they do and don't see.

And it's nothing to do with whether or note someone likes/trusts Meta. It's people being able to make their own decisions on what content they want to be able to follow and not have it decided by someone else based on their interests. If someone's friends/family/fandom has a heavy Threads presence, they can spin up their own instance and be able to follow that content themselves without it really affecting anyone else. (and without having to sign up to Threads themselves...)
