Even if I agree with so-called "liberal/pro-activist" media more than rightwing oulets, I still don't trust them one bit to look after sources properly.
Also sad that none of the parties involved (even the govt!) did not pass on to young staff in an *infosec* role some decades year old knowledge about the existence of the yellow "microdots" in large printers which I read via EFF in about 2005/6..
though curiously they are not found with modern UK/EU printers (privacy laws?)
