The protests were mostly against sexual abusers/harassers and the arbitration policies. Are you implying that most other tech companies haven't had any executive-level sexual harassers? That most other tech companies don't have forced-arbitration policies?
How many other companies openly allow their employees to organize protests through company emails and forums? Not many. The open culture is what allows people to protest.
Disclaimer: I work at Google.
Most I got for mine (leading an actual strike) was a written reprimand -probably forced by the hr manger of a certain BT division (not the one I worked in)
Did mange to change company policy and get several k people a better pension later on.
