The GPL permits a very profitable business model that RMS does not approve of: dual GPL/proprietary licensing. That is, a user of a library can accept the GPL or else pay money for the privilege of using the code in proprietary software. TrollTech, the makers of QT, have become a profitable company based on this model.

dual license model is "rms ok" Posted Jul 27, 2004 17:44 UTC (Tue) by coriordan (guest, #7544) [Link] RMS approves of the dual license business model. But Trolltech only use that model for *some* (most?) of their software. Some of their software is exclusively proprietary.Sorry I can't provide the reference, I'm running out the door as I write this. I think he spoke of this in a previous LWN.net interview. In the interview he endorsed both the MySQL and the Trolltech models, but in a follow up he clarified that hadn't known that the trolltech model was different to the MySQL one, and he retracted his endorsement.

if you need the reference: Posted Jul 28, 2004 13:58 UTC (Wed) by coriordan (guest, #7544) [Link] Below that paragraph is: ``(Footnote: RMS added later: "I later learned that TrollTech does develop proprietary software. I apologize for having mentioned it erroneously.")''
