If these people succeed they'll put themselves (and a lot of other people) out of business.
These 'protesters' are making use of technology that is here because people have been able to make money on that technology; they were able to make that money because copyright/patent protection laws allowed them to.
Some products require a lot of R&D, engineering, and development time, thus often there's quite a long time before any money is actually made (if at all).
Shorten copyright/patent protection time and investors will become quite reluctant to put any money into complex (expensive development phase) projects. We can then expect a future of easy to develop quick payback gadgets made in little shops located in the far reaches of China.
