Tell that one to Amazon. It's really not all about productively.

There's more incentives for large businesses, whether that's tax breaks, existing office space obligations or just the feeling of lording over the workers.

I don't think that will change too much. A remote company has to be fundamentally remote on all levels otherwise it'd fall apart. That kinda buy in is difficult and usually companies who start remote work best like that. As everyone has already self selected for remote work.
