It looks like you don’t really use the fediverse much at all. Not sure why you’re so bothered?
The joy of this type of platform is that if you don’t have a place to post your stuff you can just make your own. You will then have the ability to control space just like the others can control theirs.
So what you want is a space where anyone can post anything with no moderation? So make it?? I don’t understand your issue here. Is it only acceptable to you if you can go on any page you like and write anything you like?
