My guess, is that they will comply by either giving the media a copy of their "Quality Raters Guidelines", or just setup an office where the media can send staff to sit at a slow computer and view a billion lines of source code.
I love how companies can say complying with legislation would be overly burdensome. and how governments can make laws that have no technical reality. the interface between tech and law is pretty leaky and inefficient.
(That doesn't mean that all people in parliament need to be competent. Most laws are written by specialists, not MPs.)
