I think it’s worth remembering that when Win10 refers to ‘Apps’ it means anything that used to be called a program. So if you have a webcam, and assuming you have an app/program to use it for some reason, then you will need that permission enabled.
In general, apss/programs won’t sneakily fire up your webcam while you’re asleep to see what colour jammies you’re wearing. It’s the same basis for most other apps/programs/services.
This isn’t to say that some malicious force won’t try to use your webcam in order to see your jimjams, but those that would, would probably be able to change or bypass such settings anyway.
The settings are really easy to change, particularly for anyone who spends more time on a smartphone than an actual computer, which is the norm these days.
I guess that we might expect these things to be off by default, but I’m not so sure that would’ve been the case back in the earlier days of the internet if you purchased a pc with a webcam and appropriate software…
