What I mean by an answer is simply a response, from those who are to some degree in WotC's court on this issue, let alone from WotC themselves. The company has blatantly stated the opposite position to what they are currently espousing, and neither WotC nor those in the community who think it's ok for them to do what they're doing (for some definition of ok, I know there's a spectrum here) seem to have a response to that.
I don't think I have seen anyone ACTUALLY be on WotC side here... but I know plenty here will say I and a few others have. So let me answer with the only answer ANY of us have...
When it was written it was written with the intent to be forever... it was based on other things in and around it's time, although not a word for word copy, some here say some of the language used was too imprecise. in the 23 years since (actually in the first 7 if I am not mistaken) something changed, and several of the contracts (open software license's) got challenged and changed. The NEW defualt looks somewhat different then the default did in 2000. SO today the law team thinks they can use that 23 years of change (the the OGL was not updated with) as a loop hole.
If I told you in 2000 something and 100% believed it to be true (back then I thought dinosaurs were reptiles) and today I told you something different (they be chickens) it doesn't mean I lied, it means the information I had changed... this is even harder when you realize that the people who said the first thing (dinos are reptiles) and the people who said the second (Dinos are ducks) are not the same people they just work for the same company.
The problem is simply that it's impossible to have a conversation with a corporation, because they don't answer questions.
it is also impossible to have a conversation that we ALL are in the dark on parts of it, and some parts are up in the air (even the experts can't tell us for sure who wins if this goes to a judge)... all we can do is talk it out,
