Yeah sure they're a bunch of evil criminals, so if they had the methods to cheat they probably did.

But let's say that tomorrow there are worldwide headlines about some irrefutable smoking gun evidence. Or maybe Musk goes on TV being a little bit too high, or Trump gives an interview while a few neurons too many wither and die in his skull, and they say they did it, tell us where to find the evidence, and say it was worth it and they did it because they are patriots trying to save the country. Just doubling down on the old "He who saves his Country does not violate any Law."

DOES ANYTHING EVEN HAPPEN? Who is gonna do something about it?

The absolute most extreme result I could possibly see being reality would be that Trump manages to get Musk accused and convicted for the interference. That would be just as funny as it is unlikely, but it would fix nothing.
