I don't think that's likely because they don't mention OGC or PI. In the original OGL you can only copy OGC which isn't PI (it'd be very rare for something to be both at once but conceivably could happen).
So for example, I make a setting book which has some monsters, feats, and classes in it. Let's call the setting Ruinaria.
So under
OGL 1.0a,
- ALL the mechanics are OGC - Open Gaming Content - so like statblocks of the monsters, the feats, the classes, that's all OGC. Anyone else putting the OGL 1.0a licence in their book/website/etc. can use that.
- You can use any SRD that's been declared OGC - which means the 3E, 3.5E and 5E SRDs, as well as various 3PP SRDs, but not 4E SRD.
- Now, if I say, declare the setting map to also be OGC, that also is, and anyone else can use that.
- If I say Krunkalan The Wizardbiter is Product Identity, and one of my spells is called Krunkalan's Biting Teeth, you can use the mechanics, but you can't call it Krukanlan's Biting Teeth without my permission (you'd probably just call it Biting Teeth).
And note, it's not just WotC, everyone could use this.
Under
OGL 1.1 (Commercial)
- WotC could use literally everything in the entire book, and could, if they wanted to, licence it out to others.
- You can use the 5E SRD (only) - yes I know, 1.0a already let you use that and others. You cannot use others here.
- You can only put stuff in a PDF/ePub or print format.
- Additionally you promise not to be mad with or sue WotC if they make something similar to your stuff
- There is no OGC and no Product Identity. Nothing is shared with anyone but WotC. The entire concept is gone. No-one else can write for my setting via the OGL 1.1 (Commercial) unless WotC gives them permission (and WotC can give permission even if I don't want them to!). You might be able to separately licence it out with an entirely different licence, that's unclear.
- Now a lot of people were confused because the OGL 1.1 does refer to "what used to be" OGC and Product Identity, but if you read the actual clauses, it's talking solely about WotC's own OGC (the SRD) and Product Identity (the stuff excluded from the SRD, like Beholder). It has no provision for anyone else.
Hopefully that all makes sense? Apologies if not, I can clarify. Hopefully you can see how fundamentally the two licences do not operate on the same principles, for better or worse they're totally different designs.
(NB, the non-commercial licence does have a minor share-alike clause, but the non-commercial licence is basically pointless because the Fan Content Policy - FCP - already covers anything the non-commercial would, and even OGL 1.1 says the FCP is staying.)
Under
OGL 2.0, we only have WotC's slightly vague Friday letter to go on. But we can guess, because that letter also doesn't mention OGC, share-alike, sharing, or Product Identity coming back. So the
expectation is:
- You can use the 5E SRD (only)
- WotC doesn't own of your stuff, but you promise you won't get mad/sue them if they make something conceptually similar/nigh-identical to their stuff.
- There is no sharing of your stuff except if you arrange it through some entirely separate an unrelated licence of your own.
