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.
What’s the catch?
The catch is that free services like this are run for people who need them, not people who want to save money. In my opinion it is very scabby to use something like RiseUp for potentially data intensive tasks like torrenting if you can afford a paid VPN service. Leave it for those who genuinely need it.
Technically you should be donating if you get value out of it
