>I'd say their incentives are perfectly aligned with ours
Speak for yourself. I hate advertising and would rather see that whole revenue method burn to the ground and pay the $2/mo or whatever to use my favorite services.
Ads have ruined everything they have touched (radio, satellite radio, TV, cable TV, satellite TV, magazines, highway scenery, etc) and they are well into the process of ruining the internet.
In addition to bloating every site and exposing you to higher malware risk, they encourage companies to violate your privacy as much as possible and exploit psychological weaknesses to get you to buy stuff you didn't want or need to begin with.
Google's incentives are to spread this poison so they are not aligned with mine at all.
