If the technology exists for this to work perfectly, with no risk to privacy or performance, and all it did was prevented copyright infringement and access to illegal material, I wonder how many of us would still be against it regardless.

Would this still be classed as an "assault on the internet"? Or is this really an "assault on my access to pirated music/software/movies/porn/etc" at heart?

While it is a small change, it is fairly radical to tinker with an area of hardware which has been largely unchanged since the 19th century.

There were keyboards in the 19th century??
