yes, seeding works too, with no port forwarding. With mullvad, it just works and with proton I have to enable "moderate NAT" sometimes, but seeding works without port forwarding, it always has

Only because you're seeding to people that have port forwarding active. You can't seed to people that are running the same setup as yourself.

Port forwarding is a huge vulnerability. With proton it's not as much of a vulnerability, but it still opens a lot of shit that should stay closed

whatever the case is, I'm able to seed without port forwarding

You're opening a port in your VPN connection so no there's no "huge vulnerability" (even without a VPN you're only opening a port to your torrent client) and as mentioned, you're only seeding to people who have port forwarding set up. If more people run without it like yourself, the whole system breaks down.

What do you think it makes you vulnerable to?

When you are not port forwarding you can only download from users who are actually port forwarding, or am I incorrect?

You are right

Partially, it's accurate when using the BT protocol. However if you use μTP (Micro Transport Protocol), it has “support for NAT traversal using UDP hole punching between two port-restricted peers where a third unrestricted peer acts as a STUN server.”

I just said twice that everything works fine as long as "direct" connections can be made. if your torrenting client says that's happening, everything is working fine
