This paper presents the results of a laboratory study involving Mailvelope, a modern PGP client that integrates tightly with existing webmail providers. In our study, we brought in pairs of participants and had them attempt to use Mailvelope to communicate with each other. Our results shown that more than a decade and a half after "Why Johnny Can't Encrypt," modern PGP tools are still unusable for the masses. We finish with a discussion of pain points encountered using Mailvelope, and discuss what might be done to address them in future PGP systems.

The recipient computer needs to have the software installed to be able to decrypt.
Did you actually read the article? Or at least the section I refer to?

And if you were able to send to them, the recipientsalready had their key published, which they wouldn't do if they had no software installed to decrypt. Therefore, that is another Non-Problem
(You can not send encrypted email to someone who has never set up a private/public key pair. The tools won't let you do that.)
Seriously, they picked a lame package, that none of the participants was familiar with.
No, you are mistaken. I've always had this sig.
