Geofencing is not exclusive to Apple. Not even to native mobile apps. As you likely already known :)
While the submission does make an important point, it seems a bit obfuscated by accusing Apple exclusively.
Seems like main benefit of the side-loading was bypassing the geofence.
And while native apps provide heavier geo-attribution (thus, probably harder to fake), I'm not sure if this is solely an Android vs Apple thing.
