I'm not sure he's even out for blood, doesn't really seem to be the MO of someone who sells a company for millions and decides to take wages instead of stock just so he'd pay more taxes (he was one of the top icelandic taxpayers in 2021, but much further down the list of top incomes).
More likely wants to know where he's standing (figuratively, sadly) as he's apparently been spending weeks of the little time he still has trying to get answers from HR.
I like that he got Musk to basically admit publicly he's being fired because he's disabled and they won't accommodate him, though. Only thing I wonder about is whether Halli likely working under Icelandic law makes it worse or better than if he'd been covered by ADA.
