Mullvad is one of the most proven privacy friendly vpn services. (the cops literally confiscated their servers and came out with nothing) Torrenting also isn't the only way to pirate data (plus seeding can be done without an open port, just limits you too peers with open ports)
Mullvad is great if privacy is your only metric, but it's not unique in that respect and no port forwarding is a serious limitation in this context. I've been looking into alternatives and AirVPN and OVPN both look reputable.
You can still torrent with Mullvad, it's just gonna be slower because you have less peers. But it's still 100% doable. They don't block torrenting entirely..
“Just fine” is relative. Torrenting requires at least one side to have an open port. If you don’t have port forwarding, you’re entirely reliant on other people having their ports open instead. Even if there are 1000 seeds, if all of them have closed ports you’ll be unable to connect to them. It’s kneecapping your connections for no good reason.
That's partially correct, partially wrong. An open port is required to allow for incoming connections for torrenting over TCP.
For TCP:
If a seed does not have an open port, a potential leech with an open port shares their IP & port with the tracker. The seed regularly asks the tracker for potential leeches. If the tracker provides a leech with an open port, then the seed connects to the leeches open port. This connection then allows the leech to download from the seed.
If neither of seed and leech has an open port, no connection can be established and thus no torrenting is possible.
For uTP/UDP:
If both peers (seed & leech) have no open ports, the tracker can use UDP hole punching to temporarily open up a port for the peers. The second peer can then connect directly to the first peer's port which has been opened up by the tracker.
This only works for public torrents and with PEX enabled. For private trackers an open port is required.

Wrong, tracker provide IP and port of leechers, which is just what is needed to hole-punch. It is just slower, as the seeder fetch tracker info 1 to 4 times per hour, so by the time the hole-punched connection is established, leecher has already sucked up all the data from peers with open ports.
If you want to build up ratio on a private tracker with closed port, seeding a piece of a fat 100Gb+ torrent will do.
Without port forwarding you can only connect to those who do have it set up. Doing so yourself allows you to be a better citizen of the internet and share with people who don't know what it is.
(Caveat: I am one of those people who don't understand it and am just parroting what was explained to me when I asked about this)
Port forwarding allows you to seed without revealing your IP address. If you seed on a VPN and you don't have port forwarding, your IP is revealed to those you seed to.
Edit -- I was wrong. You can technically seed securely behind a VPN connection, but since you can't be connected to directly behind a vpn without port forwarding, you would only be able to seed to ppl who port forward, or who can be connected to directly. You would only be able to leech from everyone else.
If everyone torrented like this (behind a VPN without port forwarding), all torrents would grind to a halt; nobody would be able to seed.
See my comment here. An open port is only required for TCP connections. uTP/UDP allows the tracker to open up a port temporarily in many cases. This won't work for those stuck with ancient torrent clients.
