Cool hope they do a decent job moderating the servers they run and limiting malware exposure. I also hope they've taken steps to prevent themselves being used as a host for malicious entities to distribute malware to third parties
Well, unless someone makes an alternative, people are going to use it.
They do need to provide a lot of bandwidth, which isn't free, though I wonder how viable it'd be for someone to create a Nexus-like Website using magnet URLs and BitTorrent as a backend.
Maybe too much of a technical bar to attract users.
The issue with using torrents is longevity. You'd still want/need traditional storage backing it all. Don't want some mod to become lost media because nobody is actively seeding it.
There are JS based torrent downloaders. That would work for the normies to get files, but you'd still have to find a way to convince people to host files on the backend. It'd probably take a full-on desktop client wrapper with an embedded torrent client but that's a pretty hard sell for the average nerd if you're upfront, and probably a harder sell if you're dishonest about it.
