Not to get too political, but the last I've heard of Elon Musk is that he was speaking to/mobilizing right wing extremists at a big protest in London. I am also pretty sure he has been trying to do similar things in other European nations (for whatever reason).

It seems to me that it is a bit late to plead for "basic decency" at this moment.

But at the same time let me ask you, what has he got to lose? What financial or reputational risk is he taking by not taking any accountability?
