Google, you suck arse.
As a totaly blind user of a screen reader, having ANYTHING auto play is an excellent way to make me want to smack you upside the head with a nail-festooned cricket bat.
I can't pause the video because I can't hear my 'reader trying to read the page. I can't simply close the browser because Youtube seems to lock my system until the auto play is finished. And any ad that involves audio is an instant fail since I may not be able to figure out how to skip it due to those same 'reader limitations.
You want to allow auto play crap, I want to actualy use my computer. You insist on allowing it, I'll stop visiting any/every site that involves it.
