Read the terms of service for the sites. Who owns the data and when are they allowed to turn off? Answer: you "own" it but they can do whatever they want with your content, and they can turn off the service any time. Boot up that server in your livingroom if you want your content to live on.

Posterous : however, by submitting material to Posterous you grant Posterous the irrevocable, fully transferable rights to use, reproduce, distribute, modify, transmit, prepare derivative works of, display and produce the material in connection with Posterous and Posterous's business, but solely in accordance with these Terms of Use and our Privacy Policy.

Posterous is provided 'as-is' with no warranty of any kind. You use the service at your own risk. Posterous expressly disclaims any warranty, express or implied, regarding the site or its content, including any implied warranty of merchantability, fitness for a particular purpose, or non-infringement.

I know what the terms of service say, and I certainly know the terms of service allow Twitter to be assholes about this particular issue. They're still assholes, though, and they're assholes because they're getting in the way of their own users.
