It feels to me that there's something of a Motte-and-Bailey going on in these discussions. It proceeds like this:

Arguer: Musk is a pro-Russian asset who praised a Twitter thread in which a Russian government official predicted the fall of the West!

Respondent: That was trolling/sarcasm which Musk made clear in a subsequent tweet, if it wasn't already obvious.

Arguer: I just don't think CEOs of major companies should engage in trolling, especially about serious political topics!
