I'm a long time user of the fediverse, I can't help but say that I love the freedom of having a bunch of independent nodes all communicating, all with our different standards and so forth. It's very freeing but it comes at a cost, most instances, however hard you try, will not censor half the things you would never see on Twitter. People like Twitter because of their draconian moderation efforts, I was banned from Twitter because I told someone that a death threat was not ok; apparently Twitter decided that I since i said "shut up" that i was somehow the aggressor.
I'm tired of this idea that "Twitter's future is bleak" mentality, all because some rich guy bought it that would rather the platform be less strict when it comes to political thought. If it is the town square of the internet, it makes sense that people should be able to say what they want and be laughed at if they are being an idiot. Twitter was never a good platform in any sense of the word, it is probably now the best it's ever been, and it will be better once the active user count is under a thousand. People ruin things, don't be surprised when they ruin some mastadon instance you spend time on.
As a side note, the people that run mastadon are a bit... off when it comes to ethics, so i would recommend pleroma which has had less, egregious, errors in the past.
