"The tactics drew widespread attention starting in 2013, when Snowden leaked documents referencing these practices."
So this is what Snowden has done: he "drew widespread attention to these tactics". Before Snowden they would call you "paranoid" if you would allow yourself to mention it. Today they can not call you paranoid anymore.
And yes, it has hurt US industry reputation. Many don't trust Intel processors and Cisco routers anymore (among other products). They actually destroyed computers and internet as we knew them in the 1990'ies. It is not fun anymore to own a computer or a phone if you know that NSA can get access to it anytime they want... and you will never know if they accessed it...
