How is it misinformation? It's obvious what it was. Doesn't mean he's a Nazi, maybe he's "just" a '90s era trolling edgelord. Come to think of it, considering his X shitposts he boosts to hundreds of millions of people every day, that's a good description of him.
[To people who think he's a Nazi: yes, I've read all the arguments, no, I don't care - giving him the benefit of the doubt still makes him a gigantic shitlord who think its funny to do Nazi salutes.]
