You often see them “monetizing the brand.” That’s a nice way of saying “betraying customer trust.” They buy a company that’s known for high quality and then cut the quality. They can keep charging the high prices for a while until people realize that it’s not what it once was. After a while, higher end customers realize what’s happened and stop buying. Then the brand typically becomes a mid market brand and they start selling on Amazon to a less affluent clientele who still associate the brand with quality but wasn’t in their price range before. They usually cut quality again at this stage.
Effectively it’s burning all of the trust built up with consumers as firewood by tricking them into buying mediocre products at high prices.
