alt Hacker NewsI have no issues with it, and actually happy to see alternative implementations. Possibly because I did not use it much, but it does look fine to me. Not as a complete GPG replacement yet, since some software still depends on GPG, but a viable one, and a suitable one for most of the manual CLI usage (ignoring that its version on slightly older systems has a different interface, adding a bit of confusion; hopefully it is stable now). It was not listed among suggested alternatives in the linked article though, and from what I gather, the author would not be happy with it, either.
Since you mentioned me: what's the point? It would be one thing if you could (1) use Sequoia, (2) be assured of modern cryptography, and (3) maintain compatibility with the majority of the installed base of PGP users. But you can't. That being the case, why put up with all the PGP problems that Sequoia can't address? You're losing compatibility either way, so use an actually-good cryptosystem.
