By what measure did WotC or D&D get destroyed? The vast, vast majority of public figures in that space seem to have moved on from any opposition, including those who were most vocal about the OGL.
WotC completely got away with it. People will queue up for their new VTT and then be shocked, SHOCKED when Wizards leverages that to achieve the lock-in that they've so desperately pursued for years.
Destroyed is probably over selling it, but they did get the original OGL content and more licensed under creative commons as a concession which would prevent Wizards from attempting the same stunt again and provides rival VTT confidence in their continued ability to offer D&D and derived systems like pathfinder 1e.
