This is it, no matter what words you mute, no matter how much you block/mute users. Twitter considers it of the utmost importance that they get to push content, politics and news they consider important in a 3rd of the screen, always.
The last thing I care about in the world is what employees at Twitter consider valuable to put in the "What's happening" column.
Twitter could do with taking a page out of TikTok's and oldschool Reddit's book at making their app about me and my interests and passions rather than being a megaphone for a few insufferable bluechecks and twitter employees that I struggle to hear my interests from under the cacophony of things I do not care about.
