Its reporting outed the leaker of the NSA documents. That person, R.L. Winner, has now been arrested and is likely to be jailed for years if not for the rest of her life.
FBI search (pdf) and arrest warrant (pdf) applications unveil irresponsible behavior by the Intercept's reporters and editors which neglected all operational security trade-craft that might have prevented the revealing of the source. It leaves one scratching the head if this was intentional or just sheer incompetence. Either way - the incident confirms what skeptics had long determined: The Intercept is not a trustworthy outlet for leaking state secrets of public interests.
The Intercept was created to privatize the National Security Agency documents leaked by NSA contractor Edward Snowden. The documents proved that the NSA is hacking and copying nearly all electronic communication on this planet, that it was breaking laws that prohibited spying on U.S. citizen and that it sabotages on a large scale various kinds of commercial electronic equipment. Snowden gave copies of the NSA documents to a small number of journalists. One of them was Glenn Greenwald who now works at The Intercept. Only some 5% of the pages Snowden allegedly acquired and gave to reporters have been published. We have no idea what the unpublished pages would provide.
The Intercept, a subdivision of First Look Media, was founded by Pierre Omidyar, a major owner of the auctioning site eBay and its PayPal banking division. Omidyar is a billionaire and "philanthropist" who's (tax avoiding) Omidyar Network foundation is "investing" for "returns".
