Isn't this the same story for every moderately large company that did RTO over the last few years? It's not about efficiency, it's about shaking out some people by forcing them back into an office.

Around 2023 I was working at a company that was, at the time, just threatening RTO, and when hiring we had to decide if it was worth it to hire someone who (might) report to a different office in a different time zone. Which was not an issue at all a month before, when the company was still committed to being fully remote. The hours talking about it were a waste of my life for what, in the end, didn't even matter because they laid off most of the team six months later.
