On “FBI director Comey backs new Feinstein push for decrypt bill”

Yes. link to this video is a pretty good video for persuading people why this legislation is a bad idea. We might still be able to beat it by rallying support.

On “The Time Tim Cook Stood His Ground Against the FBI”

> The FBI asked Apple to put a build on a phone that would allow them to brute force the passcode, leaving the device and the build on Apple's premises the entire time. It doesn't matter how well it might be locked down or secured. If the government coerced them into building it, it wouldn't be difficult to go one more step and require apple to hand over the modified OS. This 1 does a great job of explaining why building a master key is just a bad idea. This is a pandora's box we do not need to open. 1 link to this video

On “Tech firms “can and must” put backdoors in encryption, AG Barr says”

If you need to explain to non-technical friends and family exactly why this is a terrible idea, CGP Grey offers an easily digestible 5-minute primer: link to this video Computers either have unbreakable locks, or no locks whatsoever. There's no stable middle ground.

On “The EARN IT act is an attack on end-to-end encryption”

…gital locks, if those locks are forced to be arbitrarily weak. The NSA would have the resources to pre-crack and cache every single encrypted signal, "just in case". The nature of the mathematical asymmetry leaves no middle ground: either every citizen has access to unbreakable locks, or no one will 0 (except for the Feds themselves, of course): link to this video 0 There is one cogent comparison to the arguments of 2A advocates here: "if you outlaw crypto, only outlaws have crypto". In fact, it's even worse: hypothetically the feds can track gun-running, and guns are (currently) non-trivial to manufacture oneself. But all it takes is a small snippet of GitHub code and/or a white paper to craft an…

On “Signal threatens to dump US market if EARN IT act passes”

…. Rather, they want to hoard that asymmetric power as their exclusive purview. No matter how well-intentioned, that asymmetry of raw power is something We The People have a vested interest in taking seriously, far beyond some abstract notion of "I want to Google ${CONSENTING_ADULT_SEXUAL_ACTIVITY} without worrying the neighbors will find out". 0 link to this video…

On “Null”

…to break into any software they can that is exposed on the internet (or possibly exposed in other ways like I have no idea if every app on my PC/Mac/Phone/Tablet is scanning my network for devices with known exploits) So, the security of my house (at least where I live) does not have to be so resilient but the security of much of my software does. link to this video…

On “Encryption Is Not a Crime”

It doesn't seem like trustworthy governments is the issue. You can't have backdoors period because they'll be leaked / discovered and used by bad actors. link to this video

On “Encryption Is Not a Crime”

That analogy breaks because a home's locked door as the constaint that it can effectively only be visited by someone coming to that door physically. On the internet, multiple crimimals can attack all doors at all times link to this video
