I think that there are some problems with the FAQ, some things that are ambiguous, some examples being a need for more precise definitions for "freelancing and business concerns" and "software engineering" in the list of on-topic. However, this is just nitpicking over a few phrases. Generally, the FAQ makes it very clear what's on-topic, at least for an initial pass of a question:
Programmers — Stack Exchange is a site for professional programmers who are interested in getting expert answers on conceptual questions about software development
The target audience of this site is a professional in the field of software development - programmer, tester, project manager, software team leader, architect, process improvement specialist, and so on. In order to be on-topic, questions are expected to draw on some combination of the education and experiences that these types of people would typically have. The rest of the on-topic definition provides examples of things that are on-topic or off-topic, and if there is a suitable site for another topic, what that site is.
Your question does fall into one of the buckets that is considered on-topic here, specifically software licensing. However, what you're asking for is beyond the experiences of professionals in software development. It's well within scope for people in this profession to need to understand the various software licenses and how they impact the use of a project under that license. It's also well within scope to understand how to choose a software license that meets particular needs, of one exists. However, the creation of a new software license (especially one that is valid and would hold up) is generally beyond the scope of the experiences and education of software professionals.
The best rule of thumb would be to ask what type of experience or education you would need to answer a question. If you need the specific education and experience of a software developer, it passes that check and it might be on-topic (assuming it's a constructive question that doesn't fall into the "do not ask" category).
