Wouldn't this at least allow for an opening in the market that can be filled by an organization that doesn't exploit drivers? If we continue to support a company that could do better without placing either legal or market pressure, no one has any reason to change.
You think the company is not aware of their exploitative behavior, they get away with it because they can. And you as a consumer, can either bring it to their notice, if you have the time and effort to do so, or you vote with your wallet.
