There are bad actors everywhere. But, as far as I can tell, there are very few bans of anyone on X, and no censorship or shadow-banning of any account. The community-notes section is available to everyone, so that misinformation can be challenged (but of course relies on people of opposing views participating). These are marked improvements over the previous regime.
All the abuses you're describing, were going on previously, it was just accepted by the majority as a good-thing, because it was only hurting "Nazi's". I'm not supporting anything the current ownership does on that basis, i'm saying we should all be fighting for a new paradigm, not just recreating the old one on a new platform.
And currently, there are very few voices standing up for a healthier interaction between people with opposing views. This will take a lot more than any technological fix, it will require an attitude shift. That isn't possible if we take our respective corners, and only come out when the fight-bell rings.
