This and the discussion here is obnoxiously bad. Facebook gave some device makers special APIs to access authorized data. This is literally no different than a web API or scraping facebook HTML, just more streamlined. What you guys seem to be objecting to is that non-facebook code was able to interact with authorized user data. But that is a necessary feature of displaying data of any kind (unless facebook owns the entire software stack). This is a non-story.
And HN's facebook derangement syndrome continues.
