that is exactly how it is being used, that you use it differently does not change that, but it certainly adds confusion
You're the one using it differently, causing confusion when you're called out on your mistake.
the principle is still valid. If I compare 1 < 5 and 5 < 7 to establish that principle, then you can also arrive at 1 < 3 even with if it was not one of the examples used to explain the principle
No, the "principle" is not valid. A more apt example would be that you're saying you can compare an apple to an orange because they're both round, ignoring that they're not the same.
just watch me, I can even say which of the two is more open according to the principles I used
And you have every right to be wrong, but don't complain when people point that out to you.
they are not redefining it under CC-BY, they either release it, or they don’t. If anything it is the OGL that defines anything it wants as IP
Except they are redefining it, because the same material is open content under one product released under the CC-BY, and closed content under another product released under that exact same license. Under the OGL, open content is open content in every product where it appears.
so just like the CC-BY then… what happened to your ‘they have to open their content’ idea?
No, not at all like the CC-BY. Funny how you selectively forgot that bit about how the OGL requires that
derivative open content must be open, whereas the CC-BY doesn't say that.
there is no contradiction, a license with less restrictions on the material licensed under it / the licensees is more open, that is the definition of ‘open’.
Except that's not the definition of open. Again, you're dying on the hill that says "the more open license is the one that lets you close more content!"
That a more restrictive license can force the licensee to release their content under that more restrictive license does not change that. The license is less open and more viral
That a more restrictive license allows for a publisher to use someone else's work, and then declare that no one else can use what they've derived from that work, does in fact change "that." A license which forbids pulling up the metaphorical ladder behind you is more open.
The ‘contradiction’ is resolved as soon as you do not use the same term for different things
You're the one saying that the license which creates more open content is less open, which demonstrates that you're using the same term to mean different things.
