Man,oh man. I'm with the OP.
He's not talking about some poor young waif who's struggling to find his voice in the world; but some fellow who's proud of using the path less practiced.
This isn't a newcomer who should be nurtured like a flower, but a guy who takes a perverse pleasure in making the poor unfortunate listeners uncomfortable.
The clues are that he does the longest versions and sings the loudest.
He's proud of watching them twitch.
We all started out as beginners. We all benefited from the forbearance and assistance of fellow performers, club sponsors, and audience members.
(I once played most of a tune during a group jam with the capo one fret too high. I kept wondering what that awful sound was. This is one of many such experiences that inform my playing today.)

There are those who can't get better. We should applaud their effort to express the music inside them at the level they can produce.

This guy sounds like he knows and is playing a cruel joke.
