Anybody that doesn't know their own vehicle's maintenance history, shouldn't have much of a say in this.

I'm thinking it's just coincidence that the diff blew in your tranny Robert. It's like buying a used car w/ 100k miles on it, immediately changing the oil, and the engine blowing up. Do you blame the Valvoline oil that you put in it? No, as you don't know what was put in it before. Until there is some significant data, showing that Redline MTL is the reason for your diff shattering, I don't think people should be so quick to jump to conclusions.
