Oh wow I just found a PeerTube account which recently started to mirror a ton of YouTube channels. I found some of my favorite YouTube channels there (Veritasium, Brodie Robertson, Broogli, The Hated One). It's worth to take a look at, maybe you can also find yours there, or if not, you can also submit channels:
