What carrier? Do voice calls work?

Currently a Pixel with an anonymous custom ROM, although I’ve got a PinePhone on my desk I need to test more.

Cell phones are incompatible with privacy. Any phone necessarily constantly sends your location to your cell provider just in order to work. But even if that’s true, there’s no reason to also let someone else be the remote administrator for a sensor node with a camera and microphone that you carry everywhere. Running a mobile OS with a universal backdoor is bad times.

Centralized name service means centralized name dispute resolution.

There’s no way to do that well, and there’s no reason to believe that some sort of new institution would do a better job than an existing institution (even a large corporation).

The single thing that might be most useful is to make the story for package manager direct downloads better. There’s no reason that yarn should need to download jquery from anywhere but jquery.com

I’ve got a couple VPSes, hosting

• Mailcow, because email is identity.
• Asterisk, because phone #s are also identity.
• Matrix-Synapse, for personal messaging even though XMPP is probably better.
• ttrss, even though it’s junk software with a jerk developer.
• A bunch of self-developed web apps

Self hosting email is obnoxious, but it’s also one of the only remnants of the traditional distributed internet that’s still broadly accepted.
