FWIW, my op is still sound. Hasbro has no financial incentive to reverse course. Only they know for sure why they did what they did (and I suspect we will never know), but it wasn't based on financials. Either way, I don't care for the reason, I'm just glad they did.
Clearly, there was a fierce internal battle of office politics here, and somebody lost HARD. We do not, and may never know, who did what or why internally (I'd buy the full blow by blow historical exposé in a heartbeat!).
But my operatio al hypothesisnis thst within WotC, there people who fall onto the Pro-Open Gaming [OG], anti-OG, and OG-Neutral positions. The pPro-OG people know that open gaming is ultimately good for Hasbro for the reasons Ryan Dancey advanced 20 years ago, the Anti-OG crowd thinks it is bad for Hasbro because of the reasons lined out in the OGL 1.2 Survey announcement, and the OG-Neutral camp (who probavly has the most power, i.e. I bet Cynthia Williams is here) are probably open to persuasion depending on data and arguement.
The initial hamfisted power grab probsvly came from. The Anti-OGL faction after convincing the OG-Neutral crowd that there was a legitimately business case and nobody would care, while the 1.2 proposal was probavly a compromise intended by the Pro-OGL faction to go over like a lead balloon and convince the OG-Neutral decision makers to change course permanently.
Now, given what we have been hearing...I wouldn't be surprised if Pro-OG WotC employees maybe even took some mass action, like all the designers demanding the CC and OGL protection or they would quit en masses and seek employment from. Kobold Press and Paizo or something.
Still, ultimately I'm sure the final motivation was financial...but this time with more long term thinking.
