All the problems I read about Twitter are basically PEBCAK.
"people say outrageous things!" okay so don't go ahead and read them. As an example, replies to Trump are always a shitfest. Don't read them.
"there are evil nazis!" okay so don't follow them.
"even if I don't do these two, other people I follow retweet those and I get to see them!" okay so mute, unfollow, or block that person.
"even if I don't do these two, other people I don't know say outrageous things or follow evil nazis" that's none of your business.
Twitter served me well for a long time, if you've tried to "figure it out" and couldn't (when it's the simplest shit ever) then just don't use it. Why should all services be catered to the lowest common denominator? The only thing I agree with is that they shouldn't show tweets other people liked in your timeline. But the rest is simply bullshit. It's like some people want Twitter to become something it's not and it's never been.
