I 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.
