If there was public evidence allowed to be released nobody would be using those algorithms obviously. The point of those algorithms is to make them hard to break for the public and easy to break for the agencies . E.g. None of your mentioned products use quantum hard encryption. It is not far fetched to assume that all the relevant agencies have access to a working quantum computer. But I doubt you need even sophisti…
I seriously doubt that agencies have more capabilities than the scientific community of mathematicians. Perhaps there are weak points in implementations, but I don't believe any agency has the capabilities to crack encryption, even some of the older algorithms. There is no evidence that a quantum computer can break classic encryption yet. Even if the agencies tried, they would not have the means to stop the spread of…

Codifying covert practices into law has the big advantage to make the whole oppressive surveillance state much more efficient. Gone are the days of "parallel constructions". Also the chilling effects of total surveillance alone might be enough to prevent the opposition to be effective.
