Microsoft will join Apple against the FBI and U.S. Justice Department, filing a friend-of-court—amicus brief—in a case going to court tomorrow. The government wants Apple to create a special version of iOS, referred to by critics as FBIOS, to break an iPhone 5c security features. The device manufacturer argues that compliance would set a precedent that would give law enforcement carte blanche with other mobile devices.

Brad Smith, Microsoft’s chief legal counsel, says the company “wholeheartedly supports Apple”—a statement the eradicates any potential confusion caused by cofounder Bill Gates. In an interview with Financial Times two days ago, Gates supported the government’s demands. I responded, calling his position a “catastrophic occurrence that demands current chief executive Satya Nadella’s official response. There needs to be clear policy about government backdoors and the position with respect to the San Bernardino shooting iPhone”. The company’s position is now unequivocally clear—presuming the legal filing fits with “wholeheartedly”.

Smith publicly disclosed Microsoft’s plans during testimony before the House Judiciary Committee today.
