Well every company just happens to be undertaking RTO at the same time so it seems to be above the exec level. I’ve seen hypotheses on here that city councils are putting on pressure to boost their local economies and another that boards of directors are pushing this as the last chance to layoff->outsource before H-1Bs are banned. Whatever it is, it certainly doesn’t appear to stem from innovative or independent executive thought.
They personally know the high exetutives in their area (not always c level). Probably the executive is knocking on doors for their political campaign. Between asking what the company wants they point out things the city wants.
