While true, and I am willing to work with (and contribute to) software licensed by GPL and other free software licenses, my own programs are all under the public domain, because I am against copyright. I believe in reducing rather than increasing legislation, in general, so that would mean is better to abolish copyright. Even so, if copyright is abolished and then someone does copy it and won't release the source code, someone can legally reverse engineer it anyways, give them a bad reputation, or whatever else it may be. Furthermore, abolishing copyright would not mean abolishing trademarks, so you can still refuse to grant permission to use your trademark. (I also think that in addition to abolishing copyright, patents should also be abolished. Trademarks should not be abolished, but perhaps its scope should be reduced.)
