This is exactly the kind of thing I'd expect from Newsom. Remember his podcast interviews with Bannon and Kirk? It was obviously a failed political wiggle to the right when he thought that was the way the winds were blowing, but fate has brought this new opportunity to his doorstep.
His motives should be seen as nothing more than political ambition. Now that he's found a worthy opponent in Trump, he's seeking to scramble to the top of the oppositional hill, the Democrats. That's where his ambitions end, just another unsuited Democrat for the current climate who wants to return things to the status quo. He'll be another Biden but this time with an undeniable scrap of charisma.
I keep screaming about how the TPM 2.0 requirements of Windows 11 are insidious due to the ability to implement remote attestation now. I don't think they'll spring the trap immediately, but it's locked and set and you'd be a fool to believe it won't happen eventually.
