I hate when elitist jerks decide my greater than 1080p phone display is somehow inadequate for showing their grand artistic vision and I'm not allowed to look at their photos of an old Mac unless I do so exactly the way they want me to.
I get not wanting to redesign everything for portrait mode, but a simple "This page was mainly designed with desktops in mind, please turn your phone to landscape" would've done the trick just as well.
Phone people don't read, that's nonsense. Just put a series of next and I Agree buttons that does it for them.
or my portrait mode desktop system. Especially when "view source" shows all of the content got downloaded, it's just refusing to render. Get over it, scroll bars exist.
