And a (small, but has a few links) blog post about it: https://signal.org/blog/i-link-therefore-i-am/ https://signal.org/blog/i-link-therefore-i-am/
- mulmen 6y agoThis is really interesting and gives me a new respect for Signal for thinking about it. After considering the options it seems Apple made a reasonable default assumption but in the case of sites that reveal information about me it is a bit frustrating. An option would be nice but, :Apple:.
- Groxx 6y agoTheir blog is pretty interesting about a lot of things like this. There's a lot of Good Thinking™ through Signal. And some super weird stuff like relying on Intel SGX for contact info... that they don't need to store, and don't let you opt out of. I basically trust them to actually do what they say they're doing, but I don't see the point of needing that trust in the first place (and there's no way to validate that it's happening, so it could change in the future and no user could tell).
