Mixi claims rights on all content

Japan’s hugely popular social networking site Mixi is in hot water this week after news [ja] that a proposed revision to its Terms of Use (ToU), to become effective as of April 1st, will force its users to agree to grant Mixi no-royalty, non-exclusive rights over all content published on the site, retroactively applicable to all content uploaded before the changes to the ToU. This means that Mixi can potentially use any content on its servers (including messages sent through its messaging service), ignoring access controls on such content, and potentially profit from it.
