It's a matter of loyalty - miners have zero loyalty and will always buy whatever their spreadsheet says is cheapest. In contrast, gamers tend to stick with brands, and if they're forced to switch due to lack of supply, their loyalty (and therefore future bias toward you company) might switch with it. So while miners may be willing to pay more money per card today, they're not worth the future loss of revenue. Like you said, you don't buy Nvidia because you're concerned about Nvidia support. If Nvidia was the only option, you would likely decide "fuck it", deal with any Nvidia problems (and become more familiar with running Nvidia) and become less concerned about Nvidia problems in the future because you have more experience dealing with them. And that means AMD may have lost future sales to you.
