Perhaps a little more "modern" then the examples from your link. :-p
But more the general notion of having the freedom of doing with technology what you want. Like build a PC, add some expansion card and hooking it up to your digital TV connection or install Linux.
More and more stuff will become automated/connected so companies and governments want the people to be less and less able to even have the possibility of messing with it or want to know exactly what you do.
Buying computer parts might be looked upon the same way as buying stuff to build a bomb in the future.
