There's going to be a significant exodus of Amazon employees once the mandate kicks in fully. A percentage aren't able to come into the office every day, due to unrealistic commute logistics. Google making this headline sets them up to catch a lot of talent at once, to the point that I suspect this may be part of the policy's intent.
it remains to be seen if it will be a net positive for amazon, but people quitting is expected and the primary reason they implemented RTO. it's right there in the public announcement.
