Ars Technica libeled Elon Musk by reporting that Musk "tweeted, then deleted holocaust joke".

While Hitler presided over a holocaust, the joke had nothing to do with that and everything to do with the fact that both Hitler and Trudeau are tyrants.

The joke itself, which Ars Technica found so offensive that they felt they should mirror it; didn't reference the holocaust in any way and thus does not pass muster as a "holocaust joke", so since they can't do anything productive like run successful automakers or aerospace companies they need to sit on the sidelines and lie about Musk to try to achieve a sense of faux superiority. 🙄
