And how much grift happens through Android side loading? (BTW, I hate that weasel word used to vilify a perfectly reasonable activity.) Practically all grift on Android happens through apps on the Play Store. People who know how to 'side load' are also usually careful and smart enough to think about what they're putting in. That's not a useful target for grifts either.

As somebody put it, Google goes after others without cleaning their own house first. It's just abuse of power at this point.

Are Debian repos a viable grift target?
