Musk is the least of my concerns, I can ignore his account if I cared that much. I can't really ignore that a lot of higher quality accounts have been interacting less because Twitter has become a technical mess, fucking up their timelines and notifications. This sort of loss is quiet, and slow. You only really notice it when it's too late, when your feed is nothing but mindless ads and random accounts you never followed shilling the latest thing on amazon.
The only reason most larger accounts are still "active" is because nobody wants to have to rebuild elsewhere without strong commitment from platform owners - and outside of Tumblr, nobody has really done that. Except maybe now with Substack, we'll see.
