Not mentioned in the article is how to deal with the encroachment of backdoors worldwide. If we allow the US to have a backdoor, we've allowed the principle of backdoors in general. What's stopping the UK asking for its set of keys? Still OK? They're allies after all. Where does it get uncomfortable for people? France? India? Israel? Saudi Arabia? China? Once the principle is there for it to be done technologically, businesses will be faced with the choice of allowing multiple backdoors or not doing business in those countries at all. And if you do accept all these backdoors, now you've got dozens of potential security holes. Not to mention you have absolutely no guarantee that any of these countries are genuinely going to decrypt just for "national security". Giving their native companies access to your corporate data would be a huge boon.
