I wonder how much of this "ISPs are not cooperating by putting in backdoors" is actually just "ISPs putting in back doors doesn't make any sense and wouldn't help."
Also, from what I understand, what Snowden leaked about the NSA being unable to break encryption without a backdoor wasn't really news. From what I've seen, I don't believe that the NSA recruits "the best and brightest" or anything, and regardless, they have not made secret discoveries that would overturn entire branches of mathematics. I think most people who are familiar with encryption understand this. If the larger body of mathematicians, computer scientists, FOSS advocates, and libertarians all believe an encryption method is unbreakable, it probably is.
There shouldn't even be a debate about encryption. Making it harder, but not impossible, to encrypt information might affect the security of your average user, but the sufficiently interested "bad guys" are probably always going to figure out how to do it, even if they have to use TAILS instead of PS4s. Surely that's easier than smuggling AK-47s. In principle, properly used encryption will always be unbreakable, and "doing it the hard way" will always be just as easy.
