Wrong. Win and Apple are of course backdoored by the NSA and so on, but Linux isn't. If you read the article you linked to you will understand that the NSA approached Linus Torvalds (the inventor of Linux and still one of the developers) to make a backdoor - but he didn't. That's simply because Linus doesn't own Linux - he can't decide on his own what to change. And Linux is open-source and devoloped by a huge load of developers - nobody, not even Linus, can implement a backdoor without anyone noticing.
That's why Linux is safe and will stay so.
Smartphone Kill Switch Could Become Federal LawOn Thursday, US Senators Amy Klobuchar (D-MN), Barbara Mikulski (D-MD), Richard Blumenthal (D-CT), and Mazie Hirono (D-HI) introduced national legislation to require a way to disable smartphones remotely. The goal is to deter theft and protect consumers, but this defense against thieves might come with greater vulnerability to hackers, according to a mobile industry trade group.
WITH CELL PHONE THEFTS SURGING, KLOBUCHAR, MIKULSKI, BLUMENTHAL, HIRONO INTRODUCE LEGISLATION TO REQUIRE A KILL SWITCH ON SMARTPHONES TO DETER THIEVES, HELP PROTECT CONSUMERS [from themselves.]
The way I see it, this comes from the school of never-let-a-crisis-go-to-waste, in this case, blame thieves who've taken advantage of idiot consumers to advance an agenda.
Make no mistake, next are all internet-connectable devices, the same devices currently used to remit payment freely, i.e. Bitcoin.
That's just...

I can't find words for this. What's next? Every door of the world should be openable by the government? Every camera should be viewable? "The land of the free"? My ass.
Well, if you think about it... What about implementing a kill-switch into the heads of new-born babies? They could be stolen too! Great idea!
