The memes about him have been a lot less derisive, and recently they are semi-positive towards him/meta, people were reasonable in the response to his green screen grilling video and there are jokes about them changing the Threads logo high up on lemmy, etc. And he registered an X logo as trademark to potentially counter Musk.
But honestly we might never know. I doubt they went to work for someone as self-destructive as Musk.
