I don't think that's too surprising TBH; Google want the same things Microsoft want, just for themselves and for Microsoft to not get anything. All of these Big Tech companies hate each other more or less, but they play a lot of the same games when it comes to bribing lobbying and whatnot.
But considering Google's not the one out buying huge 3P publishers (or trying to), them being against Microsoft's attempt to do so just incidentally puts them in a similar camp as companies like Sony when it comes to the issue.
Could be; several people ITT have mentioned as such. Regardless, I'm going into it the same way I did with the CMA; expecting the deal to be approved, but ready for my jaw to hit the floor if it's not.
Guess MS haven't been paying him that well if he's campaigned for them for years but an ABK deal going bust puts him debt.
Or maybe he's just bad with his money. Or has a gambling problem. Wouldn't wish any of that to be the case but like you said, he's become unhinged on Twitter. He's making Lulu look like a professional saint by comparison.
