There may be an opportunity here for a plugin that auto-reports violations in some way that can then be used in lawsuits against these companies. Obviously there are privacy concerns with something like this but there may be ways to anonymize the data or otherwise preserve privacy meaningfully. There is 'company X is doing bad thing' and 'company X did bad thing, provably, this many times to these people'.
For legal work you need a controlled forensic environment, this is evidence gathering in the same way a crime scene is. We've developed a lot of proprietary methods to ensure clean-room conditions.
