Hmm. By "we" I assume you mean customers, not third party publishers.
But... is WotC's virtual control of the third party market really in the interests of customers? If we get to the point where any 5E compatible product needs WotC's blessing (by which I mean inclusion on D&D Beyond, as the post I was replying to indicated) to be viable, as consumers won't use it if it's not there, is that any different to their OGL 2.0 goals? Did "we" win?
I guess that depends on what we wanted! If we wanted a wide, robust, diverse, plethora of hundreds of 5E compatible options free of WotC, I suggest that maybe we didn't--those products will struggle to be viable, and I submit that we'll be poorer for it. If we wanted the third-party 5E market reduced to a small handful of third party publishers working directly with WotC, then I guess we 'won'--and so did WotC!
Then again, maybe the result will be that those not chosen, who would have made third-party 5E material, will be forced to make their own systems instead, and the current 5E-ification of the market will become more diverse again, and not every TTRPG Kickstarter will be 5E-powered. Who knows? I certainly don't!
