I think some related arguments to your point are that you could say ISPs don't do enough to prevent pirated content from being transmitted on their networks or that Muslims don't do enough to prevent Islamist extremists in their communities. These claims might be true, but should companies or governments be stepping in to solve these situations? Who is mandating that they need to be "solved"? What are the consequences of solving things these ways? Could there be more nuanced implications than the solving of the thing they're trying to fix on the face of it?
