All these silicon valley companies share the same "culture" as far as I can tell. Mozilla just got caught out at it.
If there is a browser firm out there who will explicitly stand by an executive who supports traditional marriage, please show me. I will switch to their product at once.
Until then I see no need to drop Mozilla for another company that enforces the PC dogma in a less public way.
Early in my career (70s) I had the opportunity to relocate to the Silicon Valley area. Something told me that it was not in my best long term interests to do that.
While I’m sure I would have made a lot more money over my lifetime, I’m glad I avoided that place.
A company with left wing PC views is one thing. Actively pursuing a totalitarian policy to punish those with differing thought (as Mozilla is doing) is quite another.
