I think the issue is that many sites use screen size (e.g. max-width, max-height) as a proxy for things like "is this a touchscreen device", instead of using the media queries designed for that, e.g. (pointer: course) and (hover: none). I understand _why_ things are done that way; it's far easier to design and test for three or four different screen sizes than it is to design for dozens of different combinations of screen size, pointer types, and screen orientations. Still, I get why some people might be frustrated about UI density _decreasing_ to accommodate a touchscreen when they reduce the size of their browser window on desktop.
