This is a fringe view, in my estimation. Websites do not follow one HIG, people are used to variance. Also, when it comes to Apple, they tend to double down on outright stupid decisions, whereas Android is just a so much of a mess that native does not really mean anything. If you want to make something cool, the basket of native widgets will not get you far either. In general, do not stray away too far from the users expectations (which may well imply not following whatever the HIG says) and they will accept you. The platonic idealists will never be happy under any circumstance, so do not optimize for them.
