Riseup vpn is a free, donations based VPN, that doesn’t require an account and has no logs policey. They doesn’t have lots of serves like Protonvpn for example but they’re running for years and support P2P, so if someone is too short for paying for a VPN, I think its a pretty good for some use cases.
I2P still has torrenting. They have an I2P tracker as well iirc. The problem is that it’s not as “simple” as the standard vpn+torrnet. As you need an i2p aware torrent client, proxy the torrent client, and then actually get good enough peers. For popular content sure, but the amount of people using realdebrid or other ‘streaming’ services are insane now.
