Oddly enough, the competitors to Twitter and Facebook seem to have a hard time replicating the features. I know that MeWe was missing feeds and the other stuff that made Facebook easy to use, and a lot of people switched back over to Facebook because it was too much trouble to keep track of groups individually.A bunch of other people have already tried that and failed. It's the same problem as with FB, youtube, etc. Any competing service can easily replicate features and capabilities, but the part you can't just code into it is the userbase, you need lots of people to switch to the new thing to get it off the ground. And most people don't have any reason to switch, twitter's various issues, while severe, are invisible to the overwhelming number of regular users. Those people won't switch unless they're forced to, because everyone else already uses twitter.
