This has been a can kicked for many a mile. First bush, then obama, and now trump. The undocumented and largely ignored effect of FISA is that it is quietly driving cryptography to unprecedented levels of adoption. OpenPGP is part of Yubikey now, granting the average user HSM level security for their encryption for less than $50. Google has increased their cipherstrength and offers several multifactor solutions as we…
Signal type apps hide both and are valuable, but without widespread adoption is meaningless to most people.
I'm not against any of the progress you cite, but so long as people can be targeted based on metadata they are at risk. Once targeted, it becomes child's play to bypass the encryption that most people employ, whether through social engineering or side channel attacks (beyond Spectre-type) or governmental requests/threats to cloud providers.
