> And I don’t think it’s symmetrical: WFH people don’t have a reason to insist that their colleagues WFH.

Of course it is symmetrical. While designing a complex system, I prefer talking to colleagues in person over a whiteboard. Even if 3 of us are in the same room and 2 remote, my company forces everyone to log in and chat via Zoom. Separately from our individual laptops. We are not allowed to dial in from a conference room where we can use a whiteboard.
