There are two kinds of people: Those who do backups, and those who will. What Google did in this case is inexcusable, but so is keeping all your own data in one place.
I'm also slowly degooglifying my life (and recommending the same to everyone around me). There is another grouping of two types of people: (1) Ones who don't do business with Google anymore (2) Ones who won't. That one took more incidents than backups.
