This is true. Many apps, including one I worked on, start the camera a bit earlier, with no feedback, just so it's ready to go when you use it. In my case it was starting the camera on the screen right before going to record, very purposefully. In fb's case I guess the home screen is that screen, so it's not great, but it is the only choice if you want fast camera access. So this is not necessarily a bad thing. Whether they use the feed for anything else is not something we can know I guess, but my bet is that they don't actually do anything sneaky with it besides trying to give the users a faster camera experience.

This sounds like a good use-case for an OS API: The OS could either provide some API to "warm up" the camera or allow apps to declare in the manifest that they'll likely need the camera soon after launch - then the OS could do the preloading and do it in a privacy-preserving manner. (And also give the user a central option to disable it)
