Eh, the bureaucracy was creeping in many years ago, RTO has nothing to do with that imho. Amazon has never really cared what's good for employees, and that's both a strength and a weakness, since it allows them to decide what's best for the company with no pretense of some human good like the infamous "don't be evil" motto of another giant, though I did hear that shorly after Andy took over there was an LP added that might make what I just said wrong. I think fully or mostly remote companies are doing to be slower then their competitors anyway, and you're seeing this sentiment shift across the startup ecosystem (and if amazon is going to dust themselves off, looking to more dynamic/earlier stage company cultures is probably the right way), for example: https://twitter.com/zebulgar/status/1660722639420137496?s=20
