I think this is very likely, though it's also prolonging this whole exercise by avoiding the dramatic conclusion and spreading the pain out over a longer time.

If every manager at Amazon woke up tomorrow and said "screw it, we're enforcing this policy", that would result in a mass firing event of quality talent, and Amazon would feel the pain of their policy decisions and either have to swallow that and try to move on or beat a hasty retreat and call this whole thing off. It would be a quick and decisive end to this whole debate, but instead we have month after month of employees stressed and angry while looking rebellious and unmanageable, managers stressed and frustrated while looking ineffective, and the senior leadership frustrated and looking impotent.

Someone's going to win this fight eventually, but everyone trying to find middle ground and skirt the policy just takes what would be one big fight and turns it into many months of slow unease and turmoil that's bad for everyone. I want the remote people to win this, but sometimes the way to win is the lose on purpose. Let the dog catch the car so he can realize what an idiot he was being.
