For me this fits the narrative. Encryption needs to be transparent to the user in order to become ubiquitous. I assume most people are actually reluctant to read the documentation. If the tool is not self explanatory or fully embedded in the tools people use they will not see any broader adoption. It too managed to use the tooling. But I knew what public-key cryptography is and was aware of its general concept. I do not expect anyone in my family to be able to set this up. Not without putting some time into it. And putting time into it they will only do if I pressure them to do so. So I would say: Yes you are correct that he could have read the documentation. But from a UX perspective I do not see the failure on the part of the user.
