Nobody used BitTorrent? LoL

ISPs had/have whole groups trying to stomp it out.

And it was a nightmare due to NAT even then.

It just got worse with CGNAT.

I think the commenter you’re replying to is pointing out that nobody used BitTorrent for legitimate cases. And that take is sadly correct. Despite having huge upsides, everyone just hosts on centralized CDNs, file syncing services (gdrive, Dropbox, etc).

Even Linux distros push you so direct downloads now rather than pointing to trackers.

BitTorrent only has healthy usage for content that’s untenable to host legitimately.

That is because BitTorrent has been targeted so much.

Also, hey now - I have a lot of (actual) Linux disk images, and it works well for that!
