So this "revolt" was the same as any other return-to-office "revolt"... a bunch of crying about how unfair things were on some internal social platform, and then quiet acceptance of the new-new normal. Even the Amazon "walkout" protest last week only got 100 employees to show up.
As it was pre-COVID, if you want a flexible work situation, make yourself valuable enough that you can demand it. Senior and specialized roles were frequently WFH pre-COVID simply because local talent didn't exist, even in markets like SF or Seattle.
If your role is "generic tech employee doing generic things at large corporation" you don't have bargaining power. It might not be fair, but until unionization happens, it's the way the world works.
