Guessing BlackBerry was destroyed as a consumer device because it was too secure compared to Apple/Google.
That said, BlackBerry is still very popular as secure communications device for gov't officials.
Maybe gov'ts want to keep the secure tech to themselves and not in public hands.

"Richard George, who spent 41 years at the National Security Agency before retiring in 2011 and for his last eight years was the technical director of the NSA’s Information Assurance Directorate, led a team at the agency to create a restricted version of the BlackBerry smartphone for Obama.
George, who is now a senior adviser for cybersecurity at the Johns Hopkins Applied Physics Lab, said in an interview last month with National Journal that he had a core team of about a dozen who worked on Obama’s phone, with up to 50 more who were involved with the project. After reconfiguring the BlackBerry’s algorithms and engineering, Obama got a new phone that could make and receive calls from only a handful of close friends — all of whom first had to be briefed by the White House counsel’s office and have their devices examined, the report notes. The phone could not open any attachments or send tweets."

BlackBerry wins right to sell secure messaging tools to U.S. government
• BlackBerry Ltd (BB.TO) said on Thursday it has won the right to sell tools for encrypting phone calls and text messages to the U.S. federal government, garnering an endorsement from the National Security Agency for the products.
• The tools are based on technology from Secusmart, which BlackBerry acquired in 2014 after the German startup won a contract to lock down Chancellor Angela Merkel’s mobile phone in the wake of claims by a former U.S. intelligence contractor that it was tapped by the NSA.
