I'm not leaving Twitter. If I have to use the block button more often, so be it.
Honestly, I'm not concerned about Twitter becoming more of a toxic cesspool...I am concerned about Musk firing all the good coders and *strongly* suggest that anyone with any personal information in their Twitter profile remove it and that anyone who has posted important stuff to Twitter export their tweets frequently.
My concern is Twitter becoming *unreliable*, not toxic.
I'm also not afraid to call people out because I know that if they turn out to be irredeemable, again, I can block them.
I hadn't thought of leaving as being a "fragile" thing to do, but I can absolutely see that perspective.
