I'm sure it's not lack of technical skill it's a mental block, I've helped so many people set up software that is literally clicking ok a dozen times then they're like 'oh let me print this, hang on I need to compile a firmware update and flash it using a telegraph key...' big brands have the shittiest software, but people feel they should be able to understand because it's professional but something like an open source federated social network is nerd stuff so they feel the the shouldn't be able to.
Case in point, I installed MPV on a friends laptop because VLC wouldn't play the file without crashing, the install process is super simple but they have green on black hacker terminal output instead of a process bar and you type Y when prompted instead of clicking yes -- it gave her anxiety just watching me do it, said maybe we should try uninstalling VLC and reinstalling instead... Of course mpv played the video flawlessly and used less CPU and ram doing so which warmed her to it. There's no way she couldn't have understood everything and done it herself but the fact it's not as corporate as VLC would have written it off (and wow that's a crazy thing to say, I love that there's so much great open source software that VLC is middle of the road)

But yeah honestly I doubt it matters what he knows, having him parade Infront of people saying how awfull the west is would play well to the home crowd, they can pretend to have gotten great secrets from him and he'll be given all the luxuries North Korea can spare... A small concrete room and almost enough food to live!
