That works once, for whoever is at the top of any given chain. Doesn't work so well for anyone inheriting from them.Sure, but your computer does. You put your SRD out under CC, not your book.
How have they made that plain? By producing playtest packets at least as different from 5e as 3.5 was from 3.0?That is the opposite of their strategy. They have made it plain that they are not abandoning 5e.
It was pretty clear that the 2024 edition was going to be at least a 5.5. The only question now is how/if the events of the last few weeks will change that. I suppose there is a slim chance that they will pivot to actually doing revised core books for 5e, but I would not put any money on it!
(I consider it less likely that any of the other three options - stay the course with 5.5, do a full-on 6e, or scrap the idea of releasing any new PHB etc in 2024).
While that would be nice, it is not something ORC can do. It would require legislation (IANAL, TINLA).Having a way that allows orphaned works to be more broadly used even if they are initially restricted while supported by their creator would clear up a lot of those type of problems.
