The goal I advocate is the independence of the hobby and industry from the D&D brand and the company that owns it.
To be honest, the vibe I get from reading posts on this forum is that
identification with the D&D brand and the company that owns is the predominant orientation in RPGing.
Threads about the rankings of WotC-published books on Amazon; posts that reply to discussions of non-D&D approaches to RPGing that reference sales volumes of various indie RPGs compared to D&D; posts in the General RPG sub-forum that nevertheless treat D&D and D&D-style RPGing as normative for RPGing in general. There seems to me to be an almost overwhelming tendency to use D&D as a yardstick and baseline for thinking about RPGing.
We are talking about a commercial licensing dispute. It has two elements - the commercial element, and the legal/licensing element. Despite the endless (virtual) ink that has been spilled on that second element, my view is that it is largely irrelevant.
The better legal view is that the OGL in is current form grants parties to it a power to license to new parties all the material that has been licensed to them. And the most plausible view, particularly when past WotC representations and conduct are taken into account, is that that power survives a withdrawal by WotC of its offer to issue new licences over its material.
Despite this being the predominant view of the legal situation, in post after post the OGL has been decreed "dead".
So what is the point of a revised version of the OGL? Whatever the revised wording, WotC will be able to make assertions about its powers and wishes and so on which, however implausible, are unlikely to be more implausible than some of those that occurred in the current drama. (The continuing widespread lack of understanding about the legal operation and effect of private licensing schemes helps WotC in this respect.)
The relevant dynamic, here, is not a lack of legal protection provided by the OGL but the commercial power of WotC, and the fact that so many RPG publishers have adopted a business model which puts another, much bigger, entity's copyrighted work at the centre of their own business model. And so, suppose, in the future, that WotC purports to withdraw its offer to license the SRD under CC-BY? How will that be any different from the current OGL drama?
Or consider another possibility: suppose that Paizo successfully extricates PF and SF from the WotC-based licensing regime, and starts its own new licensing regime under ORC. And then, suppose that N years down the track Paizo purports to do, in relation to the licensing of its works under ORC, exactly what WotC has done over the past month?
I can't see how changes to the minutiae of the texts of licensing agreements will affect any of this. These are commercial disputes, not legal ones. What changed WotC's mind was almost certainly commercial considerations - loss of subscription, bad press, etc. I find it almost impossible to believe that there was any change in WotC's beliefs about what its legal position was.
Which brings this post back to what I said at its beginning: the RPG hobby seems to be overwhelming oriented around a single commercial publishing house - WotC - together with a handful of others that live largely within its shadow and more or less emulate its model (eg Paizo). There are "lifestyle" reasons for this (eg brand identification in a consumption-based society). There are play preference reasons for this (eg the desire, in RPG play, to have access to an ongoing stream of high quality published stories). There are complex reasons that result from the interplay of those other factor (eg the desire to have ongoing, carefully curated "canon" stories ready to hand as part of the play experience).
I don't see this state of affairs changing in any hurry.
