A little bit of this, but also it seems like the tech industry across the board is casting their lot with the right. They have nothing left to gain by wearing the mask of a dead ideology (progressivism I.e. status quo but you only use slurs at home).

I also think part of this is personal. Zuckerberg looks at Elon and the legions of dweebs who fight to defend his honor. Zuckerberg has nothing like that. He's trying to transform from the hermit nerd into some sort of "based" influencer. He has personal illusions of becoming a celebrity politician some time in the future.
