It's really neat to see something like this still going. Torrenting is a cool technology, it's fun to download and then seed a file, knowing that now other people will get to enjoy it.
Not legal pressure, government pressure. They kept getting asked to disclose which accounts had which ports associated with then and share all the info on them they kept (which for some payment methods they do briefly). So they decided to remove the feature rather than potentially violate their founding principle of privacy and anonymity. Kudos to them. Of course f*ck the CSAM assholes who made the government get involved in this and cost us this feature.
Mostly for western developed countries where you will get fucked up by the government for pirating. ISP's in US Canada and UK will sue normal middle class people for torrenting, unless you mask your IP with the correct VPN.
Did Linux OSs move into torrents later? I'm surprised one of those isn't an older active torrent. I mean sure there's no point in actually installing those OSs now but people would still seed.
