This just means that if these laptops are going to have Windows 11, they need to have a camera. It's not that the OS will not work without it. It's just MS saying, "You need a camera on your laptop." It's no different than all Macbooks having a camera, except Microsoft is dictating the OEM market needs to adhere to that standard.
That webcam is placed on an OS known for intrusive advertising and data collection, with OEMs known for pushing pre-installed software that’s invasive, if not full-blown malware.
You’re exactly right about the facts. The problem is the perception of the theme here.
