You don’t have to feel bad for the manufacturer because tooling is expensive, but I wouldn’t expect any sympathy from the manufacturer if you’re too cheap to buy their parts either.
There shouldn't be any feels between either party. It's business, as you stated. Buy'em or don't. Personally though, I wish more companies would embrace volume sales. If AMD reduced their prices by 15-20% OR ran Speedmaster style Black Friday/Cyber Monday deals every year they would increase sales by a good margin. Question is do they want to increase sales? Do they want to be stuck with inventory if it doesn't move? AMD may think there isn't a demand because these aren't strong sellers. Maybe they aren't strong sellers because there is "good enough" used parts, maybe Mopar guys are so cheap we just won't ever buy at the rates of Chevy owners. Who knows?
