I had no idea but spent some time googling anyways.
The answer seems to be a conservative tech youtuber that once upon a time worked with linux tech.
Reddit user comments:
It’s really unsettling. He used to be a great Linux guy but now he’s just a nut.
I unsubscribed from his YT channel and stopped following him as he gradually began to drift from being a dorky goofball to being a right-wing apologist.
Don’t listen to Bryan Lunduke. He’s a middle aged edgelord that new Linux users get introduced to because of his smart-ass “Linux Sucks” series, and then as they learn more about Linux themselves they realize he’s just a douche who’s not worthy of their youtube views.
