It's weird have to conclude that none of the biomining having been done in the last decade has provoked clear and binary opinions on its legality. You can mine features on pictures you don't even own and those people you don't even know (or asked for consent). It's entirely legal. Metadata is taken in masses to surveil us all. But there's no one calling for an outright ban or regulation of such things. Or let's say it's far from mainstream and only a tiny minority that does. The usual arguments are always balanced as in: "yeah but if it was forbidden, we couldn't do X anymore." On the other side, for some tech that isn't unconsentual exploitive like crypto currencies people just simply feel like shutting it down. Here, though it arguably has use cases too, nobody cares. If it's a security in the US, it'll get shut down no questions asked.
