I get what you’re saying, but:

1. the issues lies in the bounty hunting laws not the app. Change the law, the app goes away.

2. I’d rather bad laws get struck from the books, rather than lurking mostly un-enforced in the toolbox of police to weaponize. E.g. jaywalking. A crime made up by car companies to shift the blame from cars+drivers to pedestrians, mostly un-enforced except when cops want an excuse to id/frisk/hassle a young person or visible minority.
