This comes off as excessively ranty. That said, if you replace the word "ugly" with "unintuitive", the points are mostly valid, if not particularly original.

That said, if you replace the word "ugly" with "unintuitive", the points are mostly valid, if not particularly original. #2 bothered me though, because while I've seen overly-simplified buttons that were just colored text without a border, I've never seen ones where the text was underlined. Underlined colored text is still respected as the absolute universal signifier of a link. Now, some sites do remove those underlines on links which can create interference with other sites where non-underlined colored text is a button. But still, he should've used a more realistic example of the actual problem instead of a straw-man.
