I agree that this Google practice looks dodgy to me. But the question is, what law specifically is being broken? This looks like a copyright case, and if that's the issue, then the copyright holder is the generally the one who has to bring the case in. (I believe there are exceptions such as when exclusive rights are granted, but I haven't seen a justification that they apply here.) That's what the law requires; otherwise the courts would be even more swamped.

Again, I'm not a lawyer.
