I've seen zero effort from the anti-IP movement to go after politicians or even try to reach them, and I have seen a lot of FUD and propaganda against selected companies that are determined to somehow be "evil" while other, favored companies get a pass.
I don't understand their motivations, but I'm not convinced that actual change is one of them.
Further, I am not a fan of the current system, but I have yet to see a proposal for an alternative.
Finally, isn't it hypocritical to attack people for operating under the system as it is, when the people doing the attacking are not trying to change the system at all?
Do you see google giving up its patents in any area where it has a competitive advantage?
"The Congress shall have Power [...] to promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries[....]"
It shouldn't require an amendment for the Congress to decide to exercise that power differently or not at all, especially if they realize what's happening now doesn't actually promote progress in new fields without a critical mass of open prior art.
