He means that windows is built on a fairly open system that allows too to install and manage your own drivers, updates, etc. Over the last several years MS has been trying to lock this down and be more like a managed service/phone, not a computer you own.

If the PC were to be invented today, he’s saying it would be like a phone with limited freedom and most people wouldn’t care. He’s right and that’s sad. We take for granted what we have with older versions of Windows and Linux. It is being pulled away from us and that’s why I’m trying to move off of Windows instead of go to 11.
