Charity Bot, you are right. And the whole thing about what is and is not copyrighted, patented, protected, reserved, covered under fair use, what is in the public domain, what is copy right, what is copy left, what is open source, and everything else, is and is not sometimes problematic in so many ways depending on the countries you are in and depending on many factors and I heard that Walt Disney stole some ideas or drawing, allegedly, from others that worked in him around the 1920's and Disney probably stole it and copyrighted it and that means the other man could not use his own stuff and there are thousands of these stories were copyrights were actually stolen in the first time to protect the robbers and not the actual creators as the original creators are not always able to protect and copyright their work and fair use for parodies and commentaries and other things is another issue as we have Weird Al and others and that is another thing to consider and the public domain thing is another thing to consider also. All of this is very complex and more complex than most people think as it goes both ways in so many ways in the risk and in the pros and the cons of all the laws just like how taxes have problems and welfare has problems too.
