You're assuming Google actually uses Analytics data to rank websites? I realize some people are assuming that, but I've seen absolutely NO hard evidence that it's true. The idea is pure tinfoil, IMO.
Google does get user data from quite a few sources, but as far as I know their own free Analytics service is not one of those sources. In fact, I can't see how it would make any real sense.
1. You could hide data by not tagging under-performing URLs
2. Sites that don't use GA would not be rated apples-to-apples with those that do
3. When you grant permission to Google to use GA data, it's only to use it in "aggregate form"
