Does that mean that he shouldn't care about his own experience? Maybe he should just watch American idol, listen to the top 20 pop hits and eat at McDonalds too, because obviously if he isn't in the majority, his opinion dosen't matter.
Good lord that was a hell of a leap of logic you just made. You must be tired after jumping to conclusions and attacking straw men.
Meanwhile, here in reality, the general case is what is design something for (you, btw, were describing lowest common denominator programming - a very different thing with a different, tho related, focus).
Understanding what niche you occupy is key to understanding what products and services are designed for you & which are not. Complaining that you are not catered to as a uncommon case in general purpose product is not only fruitless it’s also foolish.
