They can't prove that people who share files are in violation of copyrights/
Right and wrong isn't about proof. I think most people agree (though perhaps not you judging from your other posts) that taking benefit from another person's labor and not compensating that person is wrong unless that person gives permission for the use of their labor. That's part of living in a free market society.
