As far as I can tell none of these "alternatives" implement what is at least for me the most interesting feature of PGP: web of trust and key servers. It would be really nice to see a modern take on this. > No one was sending you encrypted emails anyway I actually use PGP for e-mailing quite often, for instance: how am I supposed to report security issues without gpg? (please don't suggest Whatsapp...)
No web of trust? I would say that’s exactly the point. For tons of applications, you don’t need web of trust at all. Using PGP when you don’t want the web of trust features is an utter pain in the ass. I want to be able to encrypt/sign and have web of trust be a different issue.
You can go with somewhat centralized trust, but that only gets you do far. Or, rather, that forces everyone to deal with that centralized source. Much like the web of trust.
