I don't worry about stuff like this too much, or stuff about the UK wanting to do stupid stuff like ban all encryption. I believe the internet is going to become more private and more anonymous as time goes on. Eventually everyone will be using the equivalent of VPNs on machines/browsers that don't give out any identifying information unless a user extremely explicitly tells it to. Or perhaps something similar to Freenet will become much more popular. We're already seeing hardware (like the iPhone) coming encrypted from the manufacturer with seemingly no way for any government agency to decrypt it forcefully. Ad blockers and tracking blockers are more popular than ever. Firefox just today released an update to help prevent trackers.
It's just a matter of time - ISPs and governments and corporations will lose the ability to track their users outside of their specific platform, and many of the platforms we use today will be replaced with P2P alternatives that make tracking impossible and aren't "owned" by anyone. I am sure the governments of the world will be livid.
