These posts are equivalent to email drafts and I would hope they would be as private. On an ad-supported, web-based service? Why? If they have an algorithm that parses my drafts and uses the gathered information to make more money to pay more engineers to build better products, I have no problem with that assuming that the data is handled responsibly. For critically sensitive data that needs to be locked down, of course this is unacceptable. But so is using an ad-supported web service for critically sensitive data.
