Sorry incomplete hypothetical, Joe shares the modification of the MF RPG AFTER Wizards withdraws the offer. And also Joe basically doesn't do much on-line. He just happened to buy my book at North Texas Con. The same with Steve.
Keep in mind if we accept
@pemerton conclusion. The OGL explicitly grants me the right to distribute the content I have modified in section 10. Th
So how is Joe or Steve supposed to know that Wizard's withdrew their offer? That is the question I am posing here. There is a logical problem with
@pemerton argument. OK Wizards offered the d20 SRD under the OGL, OK they withdraw it, OK I get to keep using. But then I can only use the rights I was granted if I distribute the copy of the OGL with work. Which say that person who get my work can also share it and modify provided that one of the things they do is bundle a OGL with the work.
See the problem with the logical implications of
@pemerton 's arguments?
As a historical note, the original author of open source licenses like the GPL deliberately designed it this way. That if you contribute content it is truly perpetual.
