My guess is just that a lot of people really like Chrome and wish they could have that without the privacy concerns. I mean honestly I'm the same, I'm just seemingly more cynical as to whether that's possible.

That plus the fact that using a chrome based browser effectively hands over a bit more control of the web to chrome. If I don't like the privacy issues with chrome, it seems like a bad idea to hand (more) control of web standards over to the company that makes it, directly or indirectly.
