True, wouldn't be too different vs just using a VPN. You're choosing to trust the Tribler tech and the Tribler exit node operator vs choosing to trust the VPN provider. Granted most VPN connections are going to have much better performance vs anything Tribler related.
There is a nice side effect of running an *arr stack against Tribler, even in 1 hop mode - Your Tribler node is much more easily pulling in new content into the Tribler network for other users to access afterwards without needing an exit node. Ideally it's just one Tribler node/user needing to pull data through the exit nodes while the rest would just pull it from you and share with other nodes in-network.
Torrents over I2P work the same way. If the torrent data isn't found within I2P and you have outproxies configured you could pull torrents from the clearnet & afterwards other I2P users just share amongst the I2P network.
