While I agree with what you are saying I have a minor nit: &quot;For websites instead, pinch to zoom exists for a design deficency, mostly for web pages not optimized for small sized screen.&quot;<p>I understand what you mean, but in the context of sites specifically disabling zoom it seems to me that pinch to zoom is a design feature and not a deficiency of traditional web pages.  Responsive helps, but there are definitely times when I wish the developers would provide only a desktop view so I can use my browser features to optimize my own user experience. (I am not representative of the general public, I know).
