I don't trust any of the VPN providers, they are all compromised by intelligence agencies. To use a VPN you are route NIC traffic through their servers where they can port mirror everything. At least some of the VPN providers use open source clients, the ones that provide an app that needs admin rights to run no fucking way would I run that (Nord, Surfshark etc)

A seedbox is totally off your machine and you just create a single ssh session to download from. There is no indication of up stream traffic from your NIC at all secure or otherwise.
