It’s an excuse to keep your product in the news/review cycle. You can’t just create a useful product and leave it at that. You have to constantly change shit so people are constantly talking about it. Why do you think iPhone keep switching between rounded and square edges? It’s not because one style is better then the other. It’s so reviewers have something to talk about. It’s why commercial OSes keep getting features no one asked for. It’s why car and truck bodies keep changing even though body lines have no effect on driveability.
