I think this is a Great wake-up call to everyone who builds on someone else's platform. You are not the master of the house - and can be kicked out at any time.

I think this is a Great wake-up call to everyone who builds on someone else's platform. You are not the master of the house - and can be kicked out at any time. One way to circumvent this is to have binding legal stuff in place, another is bring so much unique value to the platform that the owners are scared of mass defections should they break your app. With Twitter I do not see any Third-party app in this category. Only companies of the likes of Apple & Google have the necessary influence to cause Twitter to think twice before making incompatible changes. Others are toast.
