"We're also offering the option to transfer from the MPK to SF office for those people whose commute would be the same or better with that change." So wait, you'll be able to switch offices even though your team might be in the second one? What's the benefit of working remote from your team but next to random, noisy people?
A ton of teams are already distributed. The RTO makes no sense unless your team is already mostly in one office but that’s not how a lot of teams are. Tons of team are completely split up across multiple states/timezones. I think IG might be more local teams than distributed but I’m not sure.
These are reasons I can think of - they want to prevent people from doing second job, they want to maintain commercial real estate prices (even if it is artificially propped up) or most likely, it is just the good old ego thing (“you work for me, I make you do things just because I can”).
