I don’t like him. He’s angry at everything and his videos are a chore to watch. I also feel like he’s sometimes a bit out of touch (I don’t like ads or paying for digital content either, but if no one pays for it, it‘ll stop existing) and a bit pessimistic (yes, companies aren’t your friends, but not everything you perceive as negative is done out of malice, sometimes people are just not thinking stuff through).
However, I do appreciate him as a right to repair activist.
Not having to pay for hardware transcoding/tonemapping is the biggest „selling“point for Jellyfin. I used to have plex before. It worked well but I didn’t want to pay 100€ for transcoding. Never tried emby for the very same reason.
