I gotta say, that's something that's never been in evidence to me! People complained that they wanted all restaurants to be Taco Bell, people complained when they released 3.5 that it tanked all the d20 System products, the retroclone publishers (and fans) generally took a "haha suck it, WotC" attitude to the whole thing, people howled about the GSL, people cheered and mocked when Paizo used the OGL to release Pathfinder and eventually surpassed D&D in market share, people complained about the SRD 5's limited content...
In my experience, some people lionized Ryan Dancey et al, but the corporation never received any "goodwill" from the OGL. It became, if anything, a source of entitlement that generated an unending stream of PR headaches for twenty years.
And just to be clear, fork the corporation. But I wouldn't expect anyone wearing a suit at WotC or Hasbro to give two shirts about any supposed goodwill.
