I realize Apple still treats it as a truth that if people buy their products, then they must be on the right track. I'm just saying that I don't necessarily agree. When you accrue enough market power, there start to be other factors you have to account for that could be driving strong sales while hiding the fact that your customers are increasingly unhappy. By the time that unhappiness hits your profits appreciably, it may already be too late to do anything about it.

I don't really think the headphone jack is the start of some grand decline or anything. I'm just saying you can't wait a year, look at strong sales of the iPhone 7, and conclude that it was good decision to remove the jack or that you were particularly visionary to have done so.
