That's putting a value of zero on being fined (or worse). I don't think the risk is non-zero. Just takes one zealous AG to file a case against you (even if you're out of jurisdiction, there's a non-zero chance you might end up passing through at some point).
Yes, that's definitely true. I don't know what kind of vetting is performed for free apps on the Play Store, but for all we know, couldn't it be someone pseudonymous in a non-extradition country uploading via Tor?
As someone pointed out in a similar past thread, 1 coin for $0 of energy is still an infinite profit.
