If Facebook or Twitter were to shut down their public APIs it would upset a ton of people who have come to depend on applications built on them. I'm definitely not suggesting that public outcry would itself be enough to dissuade a company from making bold decisions (as Facebook has shown with the TOS and redesign debacles), but it is a little bit of insurance. Whether you choose to build an entire company (or invest in one) that depends on that little insurance holding up is a valid question. I definitely wouldn't.
