Fediverse

This post at the top of the community homepage explains and answers all of my issues.

1. The idea of the Fediverse is that you can fed with and defed from any instances as an instance moderator, OR just block a particular instance on a personal level. Right?

If yes, then why is Threads fedding up being viewed as such a big issue? I am not saying I like it. I'm just wondering what the actual issue is and what the real threat is that they pose? I read some comments saying that if Threads feds up, then they could pull the numbers and this gain some sort of majority that would lead to a control over the Fediverse... But, isn't the point of the Fediverse that people can just stay away from an instance if they don't like it and still interact with the people?

2. Also, our posts on any instance are public. So even if we defed from a particular instance, wouldn't our posts still be accessible? I read that Threads can access our information. The publicly available information on the Fediverse is mostly just usernames and the posts we make. That's available regardless of them wanting it, right?

I'm looking to understand the issue, not spark a fight. Please. Let's talk it over and not start being asses.

Remember, a different opinion isn't the end of the world.
