I would call the dramatic decline in the relative size of the peer-to-peer music "sharing" world to the iTunes world a lasting success. Steve was right that 99ยข/track was a winning proposition, but it's easy to forget how effective the RIAA's legal and technical jamming efforts were at pushing Napster and friends out of the mainstream.
Yet even now, there are still people who will screw the fans in a futile attempt to stop piracy. And even when iTunes opened, it was trivial to download anything in the catalog for free. Yet we can see how popular it is for people to do things legitimately in spite of this.
Not so sure. I've tried explaining bittorent to several non nerd friends and they all say "oh I'll just watch it streaming".
Things like this spread fast, especially among young people. The reason people stick with streams today is because they have no motivation to learn anything else.
The RIAA/MPA and friends are concerned about the 247.5 million people - less concerned about the 2.5 million people.
It's why Usenet basically contains every single media property of interest - the decent search engines for it are pretty much buried in the blacknet, and will stay there, out of sight of the 99%.
Try and purchase Game of Thrones. I spent 20 minutes looking for a mechanism I could purchase it - no luck.

All this will take is a Facebook post of "Hey, install this plug-in and you can access all the things!" and suddenly the 99% are on board.
That said, if you don't think there's going to be an installer/.reg file/some easy fire and forget way to switch a computer's DNS to an uncensored one for techies to send to their friends, you're being shortsighted.
...etc
Look how easy it is to download stuff off bandcamp or Amazon's mp3 store. People still use iTunes even though AAC is a PITA.
That myth that "this will make it hard for the 99%" thing has been trotted out during every single anti-piracy failure ever. (There have been no lasting successes.) Once the "smart cow" opens the barn door for everyone else, it's open. Every single cow can just walk right out and it will be too late when you go to close it. It's like we're playing a game where we flip a fair coin. Heads, I win. Tails, we flip it again. And yet people still think that maybe next time it will work.
Think we can make it up with even harsher punishments? Well, the Great Firewall of China leaks like a sieve. Incidentally, they also use a form of DNS blocking, as I understand it (something like spoofed NXDOMAIN replies).
