Earlier quoted context omitted.
Yep. Following standards has great side-effects all around. The same things that break sites for the blind also break it for UX-enhancement extensions like Tridactyl, which lets you click elements from the keyboard, so long as sites don't go out of the way to make clickable buttons undiscoverable. (Extreme apologies for any implied equivalence between myself and the blind.)
Blind enablement also allows easier webscraping , which is what I think Google is more worried about. It has solutions, like Google voicing out the contents, instead of doing a webpage that is so scrappable that screenreaders can parse it.
They seem to have captchas down to an art in every other context...
