Apart from the "WFH is not good for everyone" (which I agree with, and there are many situations where people actively do not want to WFH), there is also the internal company cult, which makes top management believe that people stay at a job for the vibes and relationships. It is partly true, because not going to work and interacting with people all day will make you have less regrets about leaving for another company. This is not generally a huge factor (compared to, say, salary), but it exists. Managers with a lot of company cult thinking also believe that you get more attached to the company if they can see you everyday. At my company they are shocked that engineering talent is leaving despite the great financials results, and are trying to find an explanation. Apparently the "no raises this year" policy they set 6 months ago did not enter their radar.
