If a business can't handle its own scale without negatively affecting its customers, it should probably stop growing. It's the same issue we see with Google accounts being seemingly randomly terminated.

Since that probably won't happen, heuristic usage should at least come with penalties attached, otherwise the incentives are lopsided. If an airline's overbooking heuristics fail and get you bumped, you either get put on another flight and/or receive financial compensation. If an insurance company's "heuristics" fail and deny a legitimate claim, there should be a penalty. If Google terminates your account because of a mistake, they should pay a fine. They shouldn't be allowed to have their cake and eat it too.
