We had an interesting lecture about open source projects today at work. So I went to Titanium github repository to check what kind of license Titanium is using, but could not find a definite answer.
The closest I see there is:
Commercial Support, Licensing
We give our software away for FREE! In order to do that, we have programs for companies that require additional level of assistance through training or commercial support, need special licensing or want additional levels of capabilities. Please visit the Appcelerator Website for more information about Appcelerator or email [email protected].
But that's very vague. What about commercial applications? payed applications? does a developer has to open-source his application in order to meet OSS requirements by Titanium? What about OSS that Titanium itself uses?
