Yes, it isn't strictly true, that's why I had essentially. But for the VAST majority of publishers trying to figure out HOW to differentiate it in a published work (pdf, book, etc.) is going to take more time than they want, especially if they are a first time publisher.
The problem with CC-BY is that it is essentially all or nothing for a specific document. Each publisher would essentially have to make two documents (if they had IP they wanted to protect, like a setting, town, characters, etc). It's not really a good fit for the TTRPG industry.
The difference...
By definition, the ORC makes EVERYTHING that isn't specific IP or lore info open. so I wouldn't use the word "locked" other than that anything that uses BF inherently requires you make yours open also.
I don't "think" any of MCDM's 5e releases that have used the CC-BY have released anything new into the open, but I don't have access to my PDF's at the moment.
I added a bit to my post as you were replying to it, I was just going off your original thoughts post. Once I purchased it and re-read the source, then the AON entry, and then the OGL, & ORC a couple of times.
To combine both OGC and ORC is pretty tricky to my understanding of both licenses. You...
The description in your post on that source is... wow they do NOT understand how the licenses work.
Edit: I wanted to see the source itself so purchased it. And looking through it I came to the same conclusion you did from your post, the sticking point may be just the name. It looks like they...
Note: I am not a lawyer, more importantly I am not YOUR lawyer (the your in this case is the general reference of anyone that is reading my post)
OGC material that is licensed under the OGL, can NOT be used in the ORC, under any circumstances. The licenses are completely incompatible. If you...
I'm wondering if the copyright of all the previous material isn't known which would lead to them needing replacement material? Or that they don't have full rights to the previous material per contracts?
Also, when did this company buy most of AEG's RPG line?
Plus it's also shown that the current home based mfr's will almost always increase their product price to a smaller portion of what ever the tariff is at.
Last I checked RPG books are classified as "games" not "fiction or non-fiction books" so that may not be the case. And that is going to rely on the custom inspector knowing the difference.
