They don't seem like they're the types that are savvy enough to feel like it's a problem.

There actually is a version of Windows 11 that exists without any bloat, AI or any other shit (most of the system requirements are also gone) called « Windows Iot LTSC », most of its updates are security ones, and for all I've observed it even escaped some of the crappy « windows killed itself » kinda updates. Any company can get access to it.

I don't know if they use it, but they'd be dumb not to.

It's hard to believe but there exist an entire chunk of people who don't use PCs at all (Personal Computers). Being executive level is absolutely rich enough to do that. You've someone else to do all of that.
