I have no idea why they thought this was a good idea.
Really? You’ve missed all the fuss about various security and government agencies getting cranky with the likes of Apple refusing to give access to various messaging systems on the grounds of privacy and security, saying that they absolutely cannot hand over any information because they don’t have any, it’s all completely encrypted and they don’t hold the keys.
I guess you’re quite ok with any Tom, Dick or Harry accessing your private conversations.
I’m not, I think it’s a perfectly good idea, because if there’s a back door into those apps, they’ll find back doors into even more sensitive areas, like banking, and as has been proven in recent years, once the likes of the FBI and NSA get involved, the likelihood is that info will get out into the wild, to the delight of the hacking community; remember the hacking attacks on the NHS a year or two back? That used ‘ware developed by the NSA.
