Google's not stupid when it comes to making money. They're obviously seeing an improvement with personalized ads (and the advertisers want them too) so I'm pretty sure they're working across the board. They seem to be working for me (but I don't want ads directly to my content)
The day may come when the main way to get ads targeted to your content is to sell them direct.
