The only thing that has made Twitter somewhat tolerable for me as a user it the ability to hide the most toxic and extreme users, who’s posts are always worthless. There are a whole army of users on twitter who’s only aim is to inflame indignant responses to their toxic tweets. They make posts to be provocative and draw angry responses. Posts that add heat and conflict, but never adds anything that enlightens.
I suspect many advertisers were being blocked too. Disrupting Twitter's revenue stream.
