Anecdotally speaking as a long time twitter lurker, the quality of my "For You" feed has dropped precipitously since the Musk acquisition — I am now consistently getting trashy, lowest common denominator shock/click-bait posts about race, iq, social/political violence, hitler, etc. in my feed despite the fact that I do not seek that content out and have only ever used twitter for art/philosophy/literature/tech/science etc.
If that kind of dark engagement tactic is partially what it takes for twitter to become profitable, then it will be at the expense of its dignity and soul.
