Is this all about a theme that was submitted to the Theme Repository but was rejected because of licensing issues?
No, it isn't. It was inspired by that, but I'm not trying to get anything done on the ticket because of that. I'm trying to understand the policy itself. The only thing I'm trying to do is understand.
OK - you've already been told that this is NOT the right place to raise these issues. If you have a problem with the Theme Review Team's finding, then you need to raise it with the Team.
Right. I'll remember that when I have an issue with my theme I want to discuss
Since this question is related to the ticket submitted to trac
It's not about the ticket. I know what I need to do and I'm not trying to change that. I'm trying to understand the policy and why WordPress thinks this way.
According to GNU, CC-BY-SA is not GPL-compatible:
This is a copyleft free license that is good for artistic and entertainment works, and educational works. Please don't use it for software or documentation, since it is incompatible with the GNU GPL and with the GNU FDL.
I could link many other sources that discuss the GPL-incompatibility of all CC licenses, but this should be sufficient.
Please link the other sources or at least summarize the reasoning presented in them. Because I'm not asking if WordPress.org thinks they're incompatible. And, if you read my earlier post, that quote is not sufficient. That quote states Please don't use it for software or documentation. Images within the larger works are not software or documentation, and I have pointed at reasoning from legal experts consulted by WordPress that indicates they are. Given that, what is the reasoning?
This is a topic I have researched, and I am trying to continue to research. I want to know what makes CC-BY-SA incompatible with GPL in the context I described above. No one, in the mailing list or here has even approached that issue, other than Ipstenu, who asserts that they are not incompatible in that context, which makes the question of "why" moot.
Let me repeat, I'm not talking about if. Obviously, the WordPress developer community thinks that it is. I'm not asking that. And I'm not asking for a change for my ticket. I'm asking for the why so I can understand. I'm not hoping WP will change. I'm not trying to convince you anyone is wrong.
