Why not try using open source software there is no copyright. A gentleman called Richard Stallman pioneered open source and referred to it as copyleft.
A great deal of software which relates to computers and especially the internet was developed in universities and government institutions over the years and was dispatched out to the wider world for free use, very few of these people did not get nore did they ask for any money.

Your open letter from Bill Gates was interesting as his implication is that if you pay for it you will get good software which is not necessarily the case. I paid for some pretty rubbish software and used some pretty excellent free software.
Though I have to agree that reselling copies should get you run out of town.
