Comment Google Always Said Other Use Cases Were Ok (Score 1) 105
Since at least when I started working on AutoInput Google have said that accessibility services could be used for other situations other than to help disabled people. Even now this page lists other use cases: https://developer.android.com/...
You can see how there's a note there:
Note: Your app should use platform-level accessibility services only for the purpose of helping users with disabilities interact with your app.
This note was only added very recently. Check out this version of the page from July: https://web.archive.org/web/20...
This means that until a few months ago developers were using these APIs exactly how they were meant to be used: in a way that helps people use their devices in situations that they can't physically touch or otherwise handle their Android device.
