If more people sell their outdated apple device s, it will bring down all other apple device. The lower the prices of apple devices become, the unlikelier people will buy apple devices because one reason people keep buying it because they think higher price means higher quality which unfortunately isn’t the case. Less people buying apple products means more people buying linux in the long run. More people installing linux forces apple someday to open their devices such that people get interested in buying their devices because they can install linux on it. That day is not yet today
