What makes you think consumers would want to trust them again after they were abandoned previously? Consumers would rather vote with their wallets for companies that are going to continue giving them good deals. The only reason Micron has a chance to pivot back to consumer RAM is because there's not much competition, but that could change if the Chinese RAM manufacturers can make inroads into western markets and continue their rapid technological growth.
Because there isn't room for reputation here. The RAM works, or it doesn't. It costs a certain price. Do you want to spend more money, or less money?
