All it takes to keep Google from spying (apart from not using any of its products directly and not having a Google account) is a well-targeted block list on your router and in your ad blocker. They'll probably still be able to glean some data about you but it will be sparse and more or less useless for ad targeting - or maybe it is useful in that it tells them that 'you' don't like nor look at ads?
