I hate everything Musk is associated with and I have never and will never spend a dime in the epic game store. That said, I’m willing to stretch pretty far to say this quote might be more about his favoured type of reprehensible speech than csam:

All major AIs have documented instances of going off the rails; all major AI companies make their best efforts to combat this; none are perfect. Politicians demanding gatekeepers selectively crush the one that’s their political opponent’s company is basic crony capitalism.

He wouldn’t have a leg to stand on if Musk ignored/laughed off the whole thing instead of stupidly threatening the users posting the images but I guess that’s the least we can expect these days instead of actual accountability.
