I couldn't use the open content of Traveller20 whose publisher passed away a few years back and is sadly no longer around to update the license.
I understand not trusting WotC more generally, totally get that, but then this is all probably moot, you may just be team ORC.
It is not just about new content. It is about not surrendering the right to build on 23 years worth of creative content. I realize it is a fine distinction between being allowed to keep a work and using the work. But it is an important one, and one that will have ramifications down the line. As it does for other creative fields. I recommend the below as a starting point for the larger issue.
Assuming that we are talking about new work licensed under 1.2. It is not as good of a deal as the OGL 1.0a, Creative Commons, or any number of other options I have. And I have no desire to require folks to submit to my moral judgments when sharing the content I make. If something arises then I will deal with it then and in accordance with the circumstances. As I have already done in the past with the incident I related.But otherwise, is there something you wanted to do and can't do under 1.2?
