It's supposed to be "Why does Google want...". As a non-native English speaker myself, I cringed and am wondering if this article with a grammatical mistake in the 4th word of the title is worth reading...

I eat, you eat, he eats

I do eat -> Do I eat

You do eat -> Do you eat

He does eat -> Does he eat (and not "does he eats")

I'd drop the 's' in 'wants' and keep the rest. Or drop 'does' from the sentence and remove the question mark instead.

Should be "want" instead of "wants".

Probably do vs does.
