I didn't downvote you (in fact, I can't, since you were replying to me), but:

Your post was snide. Snide remarks are commonly downvoted on HN, regardless of their accuracy.

Regarding your follow-up, you're taking a very simplistic view of Google that doesn't really capture reality. Google obviously builds lots of technology that doesn't directly affect advertising revenue. Most decision-makers at Google are not asking "how does this affect advertising revenue" for every decision. You'd know that if you ever worked there.
