That hasn't worked out so badly for them. Their trackpads don't have two buttons, either. And in line with the analogy, Apple doesn't prevent you from using a mouse with two buttons: you can buy other input devices and use them with a Mac if it has the appropriate drivers. In this case, you just need to buy an adapter.

Edited to add: By the way, please don't read me as saying you're wrong, or naïve. If it's coming across that way, it's poor writing on my part. I don't realistically see a way for Apple to handle this in a way that's going to push the industry in the direction it wants it to go and please everyone at the same time. There's an element of truth to a tweet I saw the other day: I paraphrase "It's not a MacBook release without someone complaining about ports."
