Meh. I don't know about OP but where I live ISPs are forced to relay the legal notice, but nothing more happens. There is no prosecution and nobody will knock on my door.
I have been torrenting on and off since the protocol exists and never once hid my IP. My ISP relays me the threats from the industry, I ignore them, and continue what I was doing before. Same for everyone in my country. Those that end up paying for a VPN and hiding their IP are just intimidated onto doing so, because of the threats. But again, aside from getting that threatening email, nobody will knock on your door for torrenting here.
That's excellent for their clients. I'm guessing it set a precedent and the industry stopped trying anything else.
I didn't follow the most recent developments here in Canada but AFAIK, a decade ago the industry tried to sue individuals that were "pirating", and lost because they couldn't proof that an IP could be associated with a single person, or something like that. Then the industry pretty much stopped trying to sue individuals from that point. They still send the threatening letters, but they don't do anything else because past experiences with our courts didn't go well for them.
Of course, there is a very very slim chance that the industry will try to sue a few individuals to scare others and create a new precedent, but it's going to be a civil suit because it's not even criminal here.
