I think PonMan is (with the) Entourage Development team. Thanks for joining us. Jcase was not the first one to ask for the source code and been badly treated by Entourage staff which is not admissible. Entourage MUST realize that we have common goals.
Open source is important for startup companies like you because you can grab whatever is in the open source code without paying a license fee and you can make a commercial product QUICK which you can sell for PROFIT. The only think GPL license is asking from you is to give back to community what you take by making public you code modification. This way you enlarge the open source and open source products are becoming competitive with closed products offered by Microsoft or Apple for example. You must explain this to your managers PonMan.
You can always go back to closed / proprietary source model in your devices so we will not ask to make public your source than. We are users and developers that believe in open source, this is why we purchased your products and we do not want to hurt you, on the contrary.
So please comply asap and your device will become a success.
