Now that the weekend is over Tobias...
You may be correct that WotC is delusional. But nonetheless, it appears that are going to try to "de-authorize" 1.0a via clause 9, by stating somewhere in 1.1 in that the OGL 1.1 is a revision to 1.0a and henceforth 1.0a is no longer authorized for future use.
Is it fair? Honey badger ... er ... WotC don't care
Is it legal to do so? I dunno
Actually, I have had the opportunity to look at the whole (alleged) OGL 1.1 now, and one thing that I noticed immediately is that 1.1 covers
only content in the SRD 5.1 - i.e. 5E, and soon to be 6E content or in still other words what you might describe as current D&D. Not past versions.
This can mean one of two things (well, legally it can at most mean one, but I am talking about WotC's intentions here):
a.) Either they don't care about previous works making use of pre-5th edition open content the OGL 1.0a, like Pathfinder 1e or T20. Possibly because they recognize that ship has sailed and it would be hopeless to go for...
b.) ... an attempt by WotC to retroactively remove the open content from the OGL 1.0(a) SRDs (3.0, 3.5, D20 modern IIRC) published by them and place them back into the category of "unlicensed content" as 1.1 puts it.
We'll see. Even getting away with a.) seems to be dubious proposition to me, but b.) would be downright insane. I'm guessing b.) is their goal.
But what it will certainly do if successful is lock ALL games including Cepheus from using 1.0a in the future. WotC can't take ownership of Cepheus or Traveller unless Mongoose Matt or Mr. Miller publish the base rules or something using 1.1. There is a specific clause indicating that WotC CAN TAKE said new content for no recompense, regardless of origin (system or game) simply because you used 1.1.
Not really. WotC owning the copyright to the license text has no bearing on its legal effect. They could theoretically use their copyright to keep you from using the 1.0a as a license for your own content in the future by denying you the ability to reproduce its text, but nothing in 1.1 does so.
Also, nothing in this license or any other license will give WotC the ability to make any claims on content (such as Cepheus) that never made use of any of WotC's IP to begin with.
This effectively shuts down Virtual Tabletop because guess what license Roll20 was made under?.
On the otherhand Quick Link Interative had its own Traveller virtual tabletop software
VTTs, especially those heavily interwoven with D&D content, may suffer.
Then again, in that sector, software, there are some other companies who made OGL-based video games. Including that one very popular sci-fi game that is scheduled for a remake.
I'm trying to remember, something with knights... and a republic. It was based on this really popular sci-fi franchise by some guy who sold it all to some other entertainment company a couple of years ago.
Now trying to remember the name of the new company. Started with a "D" I think. And ISTR, even if this sounds weird, they have some sort of mouse as a symbol. Anyhow, sure doesn't sound like the sort of company with the legal team and staying power to take on a giant such as Hasbro. Right?
