If they want to move away from the Bay Area and work 100% remote, they’re being offered that option - that’s a change in the contract itself, in their favor, which they don’t have to take if they don’t want to.
What's being forced upon me? If I continue to work as before, nothing changes. Working remote full time wasn't an option in my initial employment agreement either, so it does not seem like that agreement applies to this situation.
That said, I recognize the difference between ideal and practical reality of the situation.

I'm not saying you see it that way, just an outside observer here.

Facebook didn't hire engineers to work remotely.
