The idea of owning something allows you to control the use. Sometimes that control includes withholding it from market. Reference the way Disney meters out its owned materials or read Dune.
What was patented, if you read it you'd know, was an innovation in displaying information on a screen. If you are for throwing out patents for innovation then so be it. You would be flying in the face of centuries of patent law but I suspect that you don't have a problem with that.
