On the other hand, FB is inherently social. I assume everything I give to FB has a chance of being public one day. I have some private conversations, but in the back of my head is that time the UI was deceiving and made seemingly direct messages public. FB is for sharing things. Google runs my phone, my work and personal email, my calendar, and more. I think they have a better attitude toward it, hence my willingness to trust them so far, but from a standpoint of ability to be invasive, Google blows everyone else out of the water on my devices.
