Can you provide a single, concrete example of a situation where this has 
occurred, preferably the one that has had most impact on you personally 
or on projects that concern you personally?

(Sub-text: I suspect that there's a disconnect in terminology use 
somewhere, but rather than poke about at hypotheticals, we'll be in a 
better position to untangle what you're trying to achieve, how to 
achieve it, how your proposed license might address it, etc. with a 
specific example that your proposed license is intended to resolve. The 
more relevant the example is to you, the more readily you'll be able to 
communicate how you see it. If on the other hand you can't put forward 
even one concrete example, then a plausible conclusion might be that 
there's no actual problem to solve.)
