I believe the point is that given a product with sharable source code (say a spreadsheet). Person A makes major improvements to the product (adds powerful options). Person B does the same. The difference is that Person A makes his improvements sharable while Person B does not. The effect is that Person B derives benefit from Person A's work while the reverse is not the case. A product sole by Person B would have the benefit of improvements by two people while a product sold by Person A has only his own improvements. Person B is acting as a parasite. The FSF believes this is wrong. In a commercial license, the licensee agrees not to share his copy of the program with anyone. If a potential licensee finds this and other conditions acceptable, then he purchases the product. The GPL has a condition that any improvements that you make to their product also be freely redistributable. If a potential licensee finds this condition acceptable, he uses the product. GPL does absolutely NOTHING to commercial licenses. It merely gives potential licensees additional CHOICE. What can possibly be offensive about giving choice to someone? Also remember, in most commercial licenses, you are not given the option of getting source. You can not modify what you don't have. In GPL, you are given the source. Thus, you have the option of making modifications. If you find offensive the fact that your changes must be redistributable, then don't make changes. In this respect the commercial license and the GPL is identical. In one you can not make changes (lack of source) in the other you will not (having your own code redistributable is offensive). What is the big deal? Let us take the possibility that you have a source license to a product (i.e. ATT UNIX). You are free to make improvements. Your code can be under any license you choose. Remember, however, that in order to be useful to anyone, a person using your code must have access to UNIX source (if he doesn't, then you didn't need the source either. An example is someone who writes a spreadsheet). Thus, a prerequisite for your licensee is a UNIX source license. Thus, effectively ATT propagates their license. Is this any different from GPL? -- Blockley Hall, 4th floor| Conway Yee, N2JWQ 418 Service Drive |yee@ming.mipg.upenn.edu (preferred) Philadelphia, PA 19104 |cy5@cunixa.cc.columbia.edu (forwarded to above) (215) 662-6780 |yee@bnlx26.nsls.bnl.gov (rarely checked)
