Maven got cancelled, but Google now has a contract with ICE/CBP's "virtual border wall" program and is working on a big contract with Saudi Arabia, after, you know, meeting with the very same guy who had a journalist cut into pieces. Thousands of Googlers may have walked out before, but they walked back in, and haven't walked out again, even though things are just as bad... or wose.

And sure, moving to another FAANG isn't necessarily going to help, they all have those skeletons. But there is a ton of tech that isn't done by Fortune 50 companies. There's a ton of tech that is for the good of humanity or on new and innovative upstarts. The only alternative to Google isn't Facebook or Twitter.
