I was once invited to be a co-founder of a startup (by the other founder), whose business model was to build something using the API of <insert-big-social-network-company-here>. I declined, for the same sort of reasons mentioned in this comment by georgemcbay - https://news.ycombinator.com/item?id=9364391 https://news.ycombinator.com/item?id=9364391 - i.e. "yes, this fact should really give pause to people who are thinking about basing an entire company around an API, portal or other service that is 100% controlled by a large company. Any such dependency should be seen as the huge risk factor that it is." Have read of multiple other such cases where the rug was pulled from under such startups that relied on a single point of failure (SPOT) - http://en.wikipedia.org/wiki/Single_point_of_failure http://en.wikipedia.org/wiki/Single_point_of_failure I told that founder the reason why I thought his model was not a good idea, after thinking for a while and then declining the offer.
