I would absolutely be concerned about a flashlight app doing all the nefarious things. A flashlight app? Today? Still? Really? It's one of those apps that's absolutely useless since the OS provides this feature natively now. It is absolutely the type of app I would assume has no reason other than harvesting data.
You're conflating "utility to user" with "utility to developer". A flashlight app has no utility to the user, it doesn't really matter to me that it's useful to its developer (for collecting my personal data).
