Peter is a genius, so he could easily build an app—whether it’s a dating app, a game, or something else—and sell it. It happens all the time in the real world, so why doesn’t he just do that?

Peter has too much ethics to do that. So he can't out onoete someone doing the same thing with no ethical qualms
