Again, I totally understand your objection, and you're right about the potential abuses that exist. The reason I said it is better now than before, is that the abuses under the previous ownership were not potential, they were real and being perpetrated every day. So I see X as _currently_ a much better place than it has ever been in its history.
But I'm with you on the potential problems and would rather have a system that was immune to such issues. What i'm really arguing against is people who saw the previous regime as correct and just, and are looking to recreate their echo-chamber somewhere else.
Part of what it will take to create a healthy town-center, that is much better than X, is for more people to speak up for ideals of diversity and tolerance. And to fight against the very loud and angry segment of people who see censorship and authoritarian control as good things, as long as they're working in their own favor.
