That's not what the GP is saying though. You won't even bother posting to fill a job that can't e done remote, so you need to consider the volume of postings as well as the composition.
That's a fair point that the overall volume needs to be considered. And during Apr–Jul it was true that hiring volumes were subdued, and it is likely that onsite-centric companies simply weren't able to hire at all. However, job post volumes exceeded pre-pandemic volumes from August and onwards. This suggests that there was actually a change in behavior. The job post volume charts didn't make it into the article but can be viewed here: https://docs.google.com/spreadsheets/d/1jlLJkZJz3NBeyjylzTYA...
