"Lobbying" ... it's just some dude saying stuff. Yeah, encryption makes it hard for people to read messages, that is the whole point. I agree it's kinda ridiculous but they're trying to say "hey, we can better help you if we can read all your data."
First off: anybody using encryption with unwholesome motives is probably not going to heed to your "public appeal"
[To my dated field-knowledge] Encryption has yet to find a way that is time-proof. With enough hints and enough computing power, all is possible, saideth the lord unto his peoples of siliconia. And there was much rejoycing, yei. (Although, elliptic curve cryptography [still] seems to be the best solution.)
Dear European Law Enforcement:
Communication is a part of freespeech. Just because tools have become a fundamental aspect of our lifestyles does not mean we want everything scrutinized for "safety" We would rather curb the likelihood that everything we do becomes the digital equivalent of "shouting from rooftop to rooftop"
Basically, "any organization that has zero oversight or transparency becomes a risk" is your argument. Not at all Ironic?
Encryption ain't going away, and people are going to turn it on. That's what happens in the digital age. All communication should be safe end-to-end. We should strive more on bringing the human element back to the digital era by being better people. All our actions ring out into the universe, so whatever you do, do it for the love of humanity.
