It's more about being effective managers. There's tons of writing and proper follow up and prep work necessary to make remote work happen and most people aren't just that diligent to do it regularly.
Most managers especially at the top are also not the most diligent people, they have employees to do the stuff that they dislike doing so when they are faced with having to do more prep work and move at what they consider a slower speed (they are wrong, all that prep work and due diligence pays off, Bezos and Amazon are a great example of that) they recoil.
