I feel pretty comfortable with how representative the people I talk to are of Google product security and vulnerability research, for whatever that's worth to you.
This is a silly thread, but for what it’s worth, I have not talked to anyone at Google in a security role about this issue.
I’ll be more blunt. I am highly skeptical that anyone in security there quit their job over the protests. But, I have no reason to doubt that your sample supports the protests.
Do keep in mind though that most people who don’t support them are keenly aware that going near any activism topic, especially at Google, is personal and professional jeopardy. Many people think they can’t even debate these things without running the risk of being on the receiving end of the scorched earth tactics employed by activists. And I’m not even talking about conservatives (of whom I know very few in tech, if any).
It’s not that they think it’s great that Rubin got dumptrucks of money, but the mentality is that if you take any issue with any of the demands or tactics, or the frequency with which they dominate the focus of employees trying to do their work, you’re suddenly a misogynistic transphobic racist enemy of the people.
Then again, a surprisingly large number of Google employees don’t seem to understand that they work for an advertising company.
