I'll admit that as recent as a year ago or so, I still believed all of the positive press about Musk, and had mostly been clueless as to all the negative things surrounding him. I'm willing to admit my mistakes after all. Why? Because I didn't have my thumb on the pulse of Musk news, just random snippets I heard.
It bespeaks about just how extensive his campaign at making himself look good was. The general public opinion of him was still very positive back then as well. Once the twitter debacle, as well as his shift to the right became more common knowledge, people decided to put a lot more scrutiny into Musk and the things he'd done.
The Twitter debacle has put the spotlight on him, as well as revealing all the closet skeletons that were only revealed on the fringes. At this point the only people stanning Musk are the hardcore fans who discard evidence against him.
