Apparently he's always had a pretty intense and acerbic personality. There's an article in The Atlantic from 2012 called The Most Dangerous Gamer that goes a bit into his character and history.
As far as politics go, in the past he mostly seemed kind of small business owner libertarian (which, fair enough, he's sunk a lot of his personal wealth into running a game studio). He's seemingly been getting increasingly grouchy about the e.g. state of software development and society in general for some time, and over the past year or so he's started expressing explicit Trump support/appreciation. Possibly exacerbated by the development of this game and Jai dragging on, apparently getting burned by what he considers bad hires (bet he's not easy to work for tho...), and such. Though I would say it feels like it's mostly hot takes on streams or X, not necessarily very coherent politics.
But the indie game scene and many of his former associates are very left wing, and with the political climate, esp. in the US, also being what it is he's quite the pariah in many places now.
