Well, at least the way he handless the typewriter and scribbles seems somewhat performative. If it's just a draft version, he seems capable of handling the typing hammers very professionally, adding online corrections staying within margins.

Seems way more seasoned in typing, than most typist of those days. And yet, he can't find the time or patience to retype the piece without typos as a final version?

I don't know the man and don't doubt his sincerity. I even agree with most of what he's saying. But it's pretty obvious imo that this is all somewhat performative.
