I believe the OP of the comment above is talking about the fact that before his twitter ban, the last picture posted by Kanye depicted Musk in an unflattering pose. The statement by OP is mostly incorrect, Kanye did post the picture, however that was apparently after a private conversation with Elon regarding an earlier post of Kanye depicting a swastika, where Elon said to either delete the photo or be banned. Kanye doubled down, attacked Elon personally and got banned.
Note: I do not really care about either Elon or Kanye, both seem to suck, just supplying the context for the comment.
