The Air is their best-selling laptop because: (1) it's by far the cheapest and (2) it's tiny. It's also extremely outdated -- people universally love the retina screen but the Air doesn't have that either. Also, rumor has it the Air is being replaced this fall, so we won't see what features make it downstream until then.
The above is to disagree with all of your specific arguments, but I do not disagree with your implied conclusion -- I don't think the touch bar is universally loved. I suspect most consumers do not care about it one way or the other, and I think it was a mistake that Apple should kill.
Fair enough. In any case, the MacBook Pro hasn't been Apple's laptop for the masses in a long time, unlike what r0fl implied. We can't infer from its design what 90% of customers want.
