To be clear, this is just a joke, and I don't look down on direct downloading. It absolutely has its place, and sometimes I do it myself if it's just faster to download a file directly. Torrenting is just so much more convenient, though, especially when using Jackett's manual search.
Not uncommon. I run wireguard in a docker container for Mullvad and then set my qBittorent container to use the network of the wireguard container. If you do something like this you'll need to set routing rules on the VPN so the web interface of your torrent client is accessible over your LAN for the *arr stack. The wireguard docs have a decent guide on how to do this, shouldn't be a problem on OpenVPN either.
