Why is a free software project like Ubuntu is creating further proprietary web applications. We have already seen that much of Launchpad, including the code-hosting part, will now not be released as free software, and now free software users are being encouraged to sign up for a data silo.
Why is Ubuntu One (and Launchpad for that matter) not being released in a way that would adhere to the Franklin Street Statement? http://autonomo.us/2008/07/franklin-street-statement/
Services like http://identi.ca and http://libre.fm have shown that free software users will embrace free network services with abundance.
