I think it's specifically driven by the management population. Individual contributors don't seem to feel too strongly about how their coworkers want to work (remote vs. in-office). But there seems to be a large effort by managers in general to get everyone back into the office, often without any supporting evidence for why that is a good option to force upon people.

This study is not good evidence against remote work. If anything, this study is just confirming what we already know - that is, remote work happens differently (synchronously vs asynchronously).

I've said it before and so have others: the push to bring everyone back into the office is in my opinion, representative of management's own insecurities.

That argument works both ways - some people who like remote will do all sorts of mental gymnastics to defend WFH when presented with evidence that it isn't ideal.
