I remember one guy though who was far-left, very obnoxious, and useless. And he got fired/pushed out a little while after I left.
Without that, it sounds like either left-wing activists are far more common at Google, that right-wing activists are afraid to act in similar ways, or that Google enforces such policies in an ideologically slanted manner. (My bet would be on all three)
Yes, and I think this is common knowledge. Good place to look is Code of Conducts for all kind of technical groups. Their language is pulled straight from identity politics of left.
The bigger companies in particular are your employer, your restaurant, your gym, your laundry service, your transportation, your social life...
What companies besides Google and Facebook could qualify as all of those?
United Shore: their own starbucks, a gym, outdoor basketball courts.
Commvault has: ping pong, foosball, pool tables, a gym, a softball field, a basketball court, a walking trail
Procore has: a gym, catered lunches, bring your dog to work policy, fitness _classes_, massages & haircuts onsite.
Adobe: a gym
Tesla: employee lease program, shuttle services
Intel: gyms, fitness classes, spas, dry cleaning, banking.
Where you work, who you work with, and what you do, it’s all political.
This was the norm in the late 19th and early 20th century when we had party bosses. Parties/Candidates promised companies contracts, so your financial interest became your political interest.
You're lucky today that you can vote for whoever you damn well please.
