Google's services and google data collection are two sides of the same coin. Make it possible to have google services without the data collection part would expose the actual data collection taking place and worse users could start asking to be disconnected from the data collection since it's now possible.
everything you mentioned seems to me to be ad targeting data, email, email address, thumbs up, save as fav even viewing a global google docs all this is part of data collected as part of the profiling process in order to do ad targeting.
Actually I don't think there is a single you do once logged on (or registered) that is not collected to profile you. facebook even collects what you do when logged off.
"If you are not paying for it, you're not the customer; you're the product being sold." is the correct sentence [1], also you are welcome to explain why it's wrong according to you, but imho you are mistaken.
This is a common case of "If you are not paying for it, you are the product being sold.", this is what happens when you engage in careless computing and put your data on a third party remote server under their control.
Don't be careless and it won't come back and bite you.
