I suggest reading <a href="http:&#x2F;&#x2F;bits.blogs.nytimes.com&#x2F;2016&#x2F;01&#x2F;28&#x2F;facebook-to-shut-down-parse-its-platform-for-mobile-developers&#x2F;" rel="nofollow">http:&#x2F;&#x2F;bits.blogs.nytimes.com&#x2F;2016&#x2F;01&#x2F;28&#x2F;facebook-to-shut-do...</a> . I think that is a really good article describing the situation.
