Twitter reveals secrets: Details of British users handed over in
landmark case that could help Ryan Giggs

Twitter has handed over the confidential details of British users in a
landmark legal case.

There is quite a big difference between asking Twitter to release user information in pursuit of a libel action (which is what is happening here), and doing so in pursuit of a contempt of court case resulting from a superinjunction.

I'm not sure that Californian courts would be as happy to assist in the superinjunction case.
