garyc2010: I agree with many of your sentiments. I read an interesting article a few minutes ago about Tetris. Tetris clones are being taken off Android phones because of a complaint by the originator of Tetris. But, says one Tetris clone guy, the copyright to Tetris expired some time ago. And Tetris clones that don't copy the exact graphics of Tetris or its name should be all right. But even the ones that apparently violate zero copyrights are being banned. This isn't fair, but in our world, if you can't afford to spend lots of money on lawyers, in many situations you don't have rights.
