Web technology is increasingly designed to make this kind of meddling harder, not easier, for the sake of user security and counter surveillance across the web.
There is no magic bullet for stopping piracy. The anti piracy companies will happily burn down the world to support their business model. There are always tradeoffs, and there are always ways of pirating things, because there will inevitably be a guy willing to point a camcorder at his TV screen.
I think most people here believe that we shouldn’t break the web so that some anti piracy companies can sell their tools.
If people want to investigate crimes, it has never been easier. The reality is that the public is not interested in collectively fining everybody who watches football on a streaming site. Instead we get garbage that breaks people’s internet so that it’s a little bit harder to pirate things.
