From the pictures itself it seems obvious that whoever wrote this suffers from the infamous valley "if it works on my iPhone, it's standard-compliant"-syndrome.
Because, you know, it breaks horribly in most stuff I throw at it and performs horribly bad even on desktop Chrome on a dev-machine.
The difference is that when people build on cutting edge tech that just about everyone agrees will be standard eventually they help push the advancement of that technology, when people built for IE only they used tech just about everyone agreed was horrible, caused vendor lock-in and was a huge security risk. I think if it works on Chrome, Firefox, IE 10, Windows, Linux, Mac, iOS and Android, we're pretty clear of vendor lock-in.
