I think this article might be looking at this wrong. Corporations play all kinds of shell games with organizations and lawyers and there are plenty of examples where corps duck responsibility by dissolving or sometimes even reorganizing these organizations.
Just because GARM has dissolved doesn't mean this kind of movement is over... like at all. The article itself states several similar lawsuits that failed.
I liked the latest D&D movie a lot, but I guess that doesn't technically count.
