Whatever else you can say for BlackBerry, privacy and security has always been something the brand is associated with. That's in danger of being permanently tarnished following an explosive report from Vice revealing that the Royal Canadian Mounted Police have had access to BlackBerry's master encryption key for six years.
A couple of caveats here that are genuinely worth highlighting: the first is that it's not clear whether the key has changed, or indeed whether the Canadian police still use this tactic. Secondly, BlackBerry offers businesses enterprise-grade encryption, allowing them to use their own keys making them immune to this particular brand of police snooping.
It's also not clear as to what degree BlackBerry was cooperating with the police, and to what degree officers took matters into their own hands, although the documents do suggest some level of cooperation.
In one transcript, the RCMPs Mark Flynn commented that details of the encryption key could damage RIM, saying “It is not a good marketing thing to say we work with the police”.
Still, if there's one positive that privacy enthusiasts can cling to from this story, it's that having access to BlackBerry's encryption keys has obviously been victim to the law of diminishing returns, as this sorry looking graph shows:

Then again, the one positive BlackBerry has had in recent years is the security of the BBM messaging service, hence its popularity amongst rioters in London back in 2011. Take that away, and most people would struggle to find any reasons to buy BlackBerry in 2016 aside from sheer willful bloody-mindedness.
