The post is well-written and summarizes I think most major pain-points with PGP.
Comparison of all these tools to GnuPG is valid and it clearly shows not only implementation problems but design ones as well in gpg.
What I fear is future riddled with all these incompatible tools. Even if they're written by brilliant engineers and cryptographers they are not standards (e.g. IETF standards). Why is that important? For example rewriting libsignal from scratch (for example to publish it under permissive licenses) can be problematic [0].
It's interesting that you compare Riot with Conversations as Conversations feels and looks much better to me (native UI) while Riot for Android always gave me the webapp feel. But Riot works consistently on all OSes while Conversations (in my opinion the best free/federated messenger to date) is available only on Android.
