It's because although many people do work well in RTO, the vast majority don't. And the various TikTok videos showing "Day in the life of a remote worker" didn't help the cause either. I worked at a fully remote company during the pandemic and trying to get people online was almost impossible. They would disappear for hours and I would be blocked by them and it was one of the most frustrating experiences in my career.
I love working in the office, mainly for the social aspect and free food, but I need to find remote work for personal reasons. And I'm about 2 years too late because almost no one in Big Tech is allowing remote work anymore.
