You say "shady" but you don't explain why. I don't understand the distinction. I care about the quality of an app and how much it costs in $/CPU/RAM. Why should I care why it uses the CPU it uses? If someone (legally) cloned an app, cut CPU in half, and replaced have the savings with mining, why would you prefer the original app?
