Can you please link to somewhere it says that OEMs can't prevent adb from disabling system apps? They obviously can't disable adb entirely (because it's useful to Android developers), but they can probably add restrictions on top of it.

(disclosure: I co-develop apps in the android sec/privacy space) Every device branded as running "Android" must pass Google's Compatibility Test Suite (CTS) [0].

  I don't see anything in there that requires `adb uninstall com.sony.foo` to work, for example? The command should generally work, sure, but that doesn't appear to require the command should work for all stock package names.

    If you are an OEM, you may violate the spirit of the CTS at your own expense.
