Objective-C shows the advantages of the GPL. Since the writers of the compiler, NeXT, wanted to use GCC's backend, they had to make their frontend GPL'd too. As a result, there exists a public Objective-C compiler, and that has done neither NeXT nor Apple any disfavours. -- Alan Mackenzie (Nuremberg, Germany).

This is a fairly absurd hypothetical. Using Pascal's library would only save me the time of implementing it myself, and so would be worth precisely the effort that goes into making it. warmest regards, Ralph -- Raffael Cavallaro

I'm afraid this counterexample is based on the wrong idea that MacOSX is a system whose life started in 2001, after Linux. Actually, MacOSX is just NeXTSTEP, and is older than Linux, so it's not surprizing it has more web clients than Linux. After all, NeXTSTEP was the system where the web was INVENTED, and where the first web browser was ever IMPLEMENTED! > The original claim was that linux was dominating BSD UNIX because of > the GPL.

And the laser printer was first connected to the Xerox Alto, but you don't see many of those at graphic design firms. NeXTSTEP never had a significant web client share once numbers of internet users grew into the tens of millions. The numbers matched OS usage - 95% of these new users were on Windows, and the overwhelming majority of the remainder were on Mac OS. That's why NeXT had to sell the company to Apple, itself a minority player. Mac OS X has 5x as many web clients as Linux because of what Apple did with NeXT, not because NeXT was ever a popular client platform. warmest regards, Ralph -- Raffael Cavallaro

The choose non-GPL alternatives because they want their software not to be free, unlike the libraries they use. > In short, I don't think GPL licensing gets you anything additional in > terms of getting code open sourced. But history says otherwise. For example, there's a lot of code in gcc that is there because the customer was told that if they wanted their gcc extension (custom back-end, front-end changes, etc) they'd have to release it under the GPL. > I think people should avoid GPL licensing their work as a pragmatic > means of ensuring maximal adoption.

The FSF seeks to maximize freedom, so licenses code whichever way works best. Libraries sometimes have different needs from applications. Andrew. |
