Google "accidentally" harvested that data when it was trying to collect geolocation data for WiFi network triangulation, it wasn't collecting passwords and private information to use it against you. In fact, Google admitted to the breach, and implemented increased security measures as well as secured and destroyed (or has agreed to destroy) the data. I don't love Google by any means, in fact some would call me an Apple fanboy, but they didn't do anything that would warrant me stopping use of their services. This was just a mistake and they are paying the price, it was nothing that was intended to be malicious. That simple.
