Carlsen's statement didn't make any accusation of OTB cheating, only that Niemann has cheated "more - and more recently" than he has already admitted.
The reason he gave for withdrawing and refusing to play against Niemann is that given he doesn't want to play against repeat cheaters because he doesn't know what they'll do in the future.
If carleson withdrew from the tournament before he lost to Hans, I'd agree more.
But honestly, Magnus lost Hans fair and square while he had the white pieces. His bruised ego couldn't handle it. So went on to try and destroy this teenagers career (19).
Shame on Magnus.

Haha, well, much of that was CYA rhetoric. For example "my actions have sent a very clear message, and that message is I don't want to play Hans" lol, yeah, sure, that was the clear message.
I'm sure he had lawyers help him type that up... in any case, that would only vindicate his press release, not his leaving the tournament, especially since it's reasonable to believe Carlsen didn't know anything about it at the time... I mean, not even chess.com knew at the time (otherwise they would have locked him out of his account earlier, and by the way it's still not closed for cheating so... chess.com being pretty opaque about that).
