Yeah, I do @musllibc, FOSS & infosec stuff. But now is not the time for a mostly-/only-tech Twitter feed.

      https://twitter.com/CopperheadOS/status/972536015436107777 … Forbidding people from making secure devices with an immutable hardware root of trust: freedom! Forbidding killing people with drones: slavery! Today's ethics lesson brought to you by the GPL3.

      Sure, just stating the obvious that software is a neutral tool. If you take the Apache 2 license and add a clause forbidding killing people with drones, etc. it wouldn't be a Free Software license anymore and wouldn't be FSF / OSI approved. https://twitter.com/gg1729/status/972534049729376256 …

      Seriously, reviving this? As soon as every project starts adding its own fields of endeavor restrictions, you end up with no license compatibility/no practical ability to combine FOSS code. Same issue as GPLv2-only vs v3-only.

      Yes it would be great if we could get some sort of universal consensus on the right restrictions. I don't see that happening.

      Re: hw root of trust, there are totally ways to do it that leave user freedom to change or replace sw, free of vendor lock-in.

          To replace software, sure, but the firmware leading up to when the user configured key is read needs to be verified from a hardware root of trust. It's also inherently more secure to have an immutable key without relying on state. Can close most of the gap but never all of it.

          We're quite aware since we only currently support phones using an owner-controller public key to verify the OS from the late stage firmware. If we made our own device we'd hard-wire the key instead of storing it in protected state. Even if the benefits are small they do exist.

          Could sell devices where the users could blow the sec fuses to set up using their own key but that's setting up a recipe for disaster because it's too easy for people to turn it into a brick and blame the vendor.
