If you follow people on Twitter based on the quality of their activity then Twitter is incredibly valuable. My problem has never been about people tweeting things which were offensive, it was about them tweeting things about their dogs and cats all day long.
If you follow people because you like them, because you are friends with them, or because you hope they will follow you back, Twitter is a fucking disaster. There are people I really wanted to follow, but if I see 30 tweets/likes/retweets in my feed for every 1 incredibly useful tweet, they have to be unfollowed. Unsurprisingly, this approach pretty much cleans out all of the off-topic annoying non-sense, irregardless of your political views or lack there of.
The flip side to all of this is, if a lot of people follow you, the very open nature of Twitter can certainly be a problem. If you are a celebrity or a well known person and are not able to ignore what I imagine is basically a hate stream, then for your own well-being you probably should not use Twitter.
There are plenty of people who are addicted to the algorithm drip feed of content now. Snapchat and Instagram/Facebook have turned this in to a compulsive behavior and the ad revenue has followed. My guess is that as a "solution" to whatever is going on now, Twitter is going to move toward this model. When they do, I sincerely hope that Mastodon or some other open ActivityPub platform is good enough that all of the really smart people who post fantastic content to Twitter, like John Carmack and Tim Sweeney, will follow.
