This has nothing to do with being free of cost. There is GPL code that costs money, and non-GPL'ed code that you can get without paying anything. These two factors (license used for distribution, and cost charged) are not linked in the manner you assume. Second, whether software is available under the GPL is not necessarily a function of the cost of producing the software. There is expensive software available under the GPL, and there is software that must have cost almost nothing to make sold as proprietary software under very restrictive licenses. For example, I am sure that the Netscape browser was quite an expensive piece of software to build, yet it is released under the NPL, which is quite similar to the GPL. There are many different business models for the distribution of software. The old assumptions that you cannot afford to distribute "expensive" software under the GPL or similar licenses are being questioned by new announcements every day! So you may laugh now, but we will see, perhaps the last laugh will be in the other direction ... -----------== Posted via Deja News, The Discussion Network ==---------- http://www.dejanews.com/ Search, Read, Discuss, or Start Your Own
