All these patents, copyrights, trademarks and other form of memes monopolization are only slowing down cultural evolution to the disadvantage for all of us. The cultural evolution work similarly as biological. If yellow color is good for users, let is spread. Then some company will most likely add small tweak that will turn into yet another benefit and better product. The society benefits. Whereas in current system only one company benefits. That is wrong because patents etc were made to benefit the society, not some greedy companies.
