Why would they share that... come on lets not be naive here. Do they always justify every bigger decision to whole world? It just creates friction surface for various people to catch on. C suite is there to set directions, not to explain themselves to their employees.

Its like getting refused during interview process. Sharing actually why makes no sense for hiring people, no gain and potentially a lot to lose.

I don't like the situation overall or RTO at all since it markedly increases quality of my personal life (which makes me a happier employee too but nobody really cares about that) but we need to be realistic with various people's motivations.
