I don't think everyone is as-productive in a remote mode, but knowledge workers who build tangible things often can be more productive, and measurably so.
Excess Management is more visibly pointless with remote work, and naturally excess managers who contribute ~nothing hate it. For example people who manage mediocre webblogs due to be replaced by LLM content such as the author of this document. It makes those people miserable, and the majority of workers in any organization are unproductive. That's all.
