Go for it! If nobody reports things they don't get fixed.

I have found this to be true not just when it comes to companies breaking laws, but also to much more benign things. Such as reporting potholes in town or broken microwaves at work. Those can be in need of fixing for an extended period of time, yet when I report them, they usually get fixed within days. I suspect most people can't be bothered or think that surely someone else will report the issue. But that doesn't work if everyone thinks that way.
