Google already has DoD and police contracts, and their entire current day business model is about tracking people's every movements to sell them shit they don't want.

Some employees of Google may indeed be complicit in killing people, just not domestically. And their efforts are making our lives worse, it's just a bit opaque, because the effects of big data aren't always very apparent.

The search engine part of alphabet isn't the main part anymore.

Alphabet is already making the world a worse one, so any union that is okay with their employees' current jobs, and will just seek to earn them more money doing so, isn't really one I can get very excited about.

I mean, good luck for them, I guess, but I'm not gonna join them on the picket lines.

EDIT: Google does have police department contracts.

I should also reiterate that I'm not against, just... ambivalent about the alphabet workers union. It really depends on how much they'll actually put their foot down regarding the reprehensible shit alphabet is already doing. I just don't see alphabet being able to exist in a semi ethical way, because their entire business model is currently centered around surveillance capitalism.
