"E commerce apps" are very much not the sort of traditional desktop application they were referring to. Note that they add "in badly designed mobile apps, I often do."
They're referring more to things like "you can't copy the text labeling the brush width field in Photoshop" (but you CAN copy the text out of that editable field). It's a part of app design people are extremely lazy with today, as you note.
In any sensibly designed desktop package tracking app that number would've been selectable or copy-able text, like how an email subject is in a desktop email app. (Thunderbird, say.)
(Interestingly, ctrl-f to find is one that many apps/OSes have now borrowed back, with the ability to "find" items in menus through a Help menu -> Search action.)
