Assume we have a software which we developed completely ourselves from scratch. We are thinking of making the source code available to others, thus I am pondering what license to use.
My question is: would a GPL-like license covering above mentioned software (e.g., the European Union Public Licence) create an incentive to buy an exception? I read about "selling exceptions" here: https://www.gnu.org/philosophy/selling-exceptions.en.html , and here: Open-source license to prevent commercial use?.
For clarification: our software is a library that would be a building block for simulation software, so pretty much at the bottom of a software stack. We plan to sell exceptions to an open-source license, but the demand is probably not very high. I am looking for experience (not opinions) whether or not such a model would actually generate some revenue. Second-hand or hear-say experience is fine, though. Qt is one such example, but I am interested in more examples, especially in cases where there is no big foundation or company behind the OSS.
