Thank you. This phrases what I've been feeling for years (especially ever since the rush of Twitter based services). When you decide to make yourself dependent on someone else's product, and you don't get a formal partnership agreement from them, you are opening yourself up to disaster. And by no means should you expect the creator of that product to bend over backwards just to accommodate you. If you don't like their changes, or something they do interferes with your business, then leave. If you can't reasonably do that because you have inexorably linked your livelihood to that product, then that is no one's fault but your own.
