It's because RTO hasn't actually happened yet. Most companies either keep WFH or go with a hybrid solution. My theory is that the productivity boost wore off as soon as WFH became the new normal, and went negative due to obvious reasons (easier to slack off). Classic honeymoon phenomenon where everyone was ecstatic to work from home initially but got used to it and now take it for granted.
