I found the Flatpak significantly easier than any other method. The only thing I had to do was set it to run when the computer boots up to save a click.

I highly recommend configuring qBittorrent to only connect to the VPN interface, so if your VPN is off it will simply not connect to the internet at all.

Some of us still use devices that only support .mobi
