Well PC game companies could sell graphics cards, but I don't see anything in the article that assures they land in the hand of gamers rather than eth miners.
So in that regard it won't fix the problem, frankly I'm a bit surprised that AMD/Nvidia haven't started some kind of "GPU direct" system where they track the mailing addresses they are being sent to and prioritize orders being sent to unique mailing addresses with unique credit card names. Microcenter does something similar (AFAIK) for hard to stock items where its 1 per customer, and they use the CC name to validate you don't just walk out of the store and back in an hour to buy another.
Although, like the ryzen 5k shortages it feels more like there is just a general shortage, and AMD was prioritizing the higher margin goods (aka epycs to hyperscalers). So while everyone likes to blame the miners, its just as likely that they aren't really having that big of an impact overall compared with some big corps buying some higher margin part and consuming all the available volume for their machine learning/etc apps.
