Bit of a laugh coming from a resident of a Five Eyes country (as I am myself).People (and corporations) in Australia, and I believe in the US, are worried about governments wanting to collect and store metadata for national security purposes. Lots and lots of hand wringing is published in the media because of this.
When you sign up to a Google account, you effectively authorise Google to collect information about you and everything that you do on the internet (stuff is stored on your computer, in part, to accommodate this). If you use an Android phone (especially a Google phone), you also allow mobile data to be collected, willingly or not.
Odd that no one seems to be worried about a private corporation collecting information, especially one whose very existance depends on collectiing everything conceiveable about people signed in, or not, to its services. And moreover, the data is then collected, stored and used by an entity that probably isn't even from your own country.
You express concern that private corporations are collecting this information (and people are aware of this to some degree, and can take steps to mitigate the risk), yet your own government is busy spying on almost the entire rest of the world and increasingly, its own citizens, and sharing that data with other members.
And you don't even get great products like Google Search, Google Now or Google Plus in return.
In today's constantly surveilled society, being concerned about Google is close to the last thing you should be concerned about; it is way, way too late for that.
