I think you're right, and I think it will motivate those of us who want to work remotely to quit and find companies that have that as their culture and let the "back to the office" folks become more homogenized.

Currently at a hybrid company spread out across multiple offices. So all that happened was that we moved our meetings from our home offices to our open office desks.

A lot of people come to the office vs. remote question from a place where "office" means that almost everyone you ever interact with is a few dozen steps away. For many of us, it's more like thousands of miles. In fact, if I go into either of the closest offices, I know almost no one there and even fewer who are likely to actually be in the office if I drop in.
