Peertube is essentially mastodon or lemmy with videos. Its trivial to set up compared to the other two. I run a private instance so I cant talk about the rate of issues but from an experienced admin perspective, its no more of a problem to set up and run than the others.
But I too think that long term it would be great to have more user friendly setups as to enable less experienced folks to host it.
I agree. But I would go further and say if other industries didnt have more complex schemes and locked down IP (eg car manufacturing), people would def build their own shit with current tools. Its always the greed of those not willing to invest in innovation that keeps progress away. Media piracy and FOSS culture are the only real challengers to greed imo.
