Embracing a single point of failure
As Marco Arment says in this piece about Twitter (specifically, the impact of its recent whimsical change to authentication requirements, though the observation applies generally):
These are the risks that you take when you base your personal happiness or your business on a single, irreplaceable, young, evolving third-party service.
The same can be said for Facebook, or those silly "URL shorteners", or Gmail, or any number of other no-cost fad services that seem to become so popular.
Commonfolk can always be counted upon for short-sighted feelings of entitlement.
