As said, if one does not understand a medium, it’s not the medium’s fault. Same as with torrent, if you need niche-stuff like localized dubs, you’d need local forums/sites for that. Same as with private torrent-trackers. I’m not a native-tongue either, but if i want localized or foreign stuff, there are at least 3 sites where i always find the stuff. It’s just not a simple “enter name, wait, watch” anymore, just the same speed when actually downloading. I even have torrent as a low-priority fallback enabled. Didn’t trigger for years :) Also torrent’s full-speed vastly depends on age of torrents and how mainstream their content is. As if every torrent of the last decade on that tracker is shared with full-speed.
Anyhow, if you think torrent is superior, you’re surely entitled to your own opinion of course. As said, the less people that use the usenet, the better for its future.
See my other comment, this “drawback” is just based on missing knowledge. It’s absolutely the same as with torrents. If you are on public trackers/search-engines you’re fucked with the absolute mainstream-stuff. On private trackers you find what you need. Same with usenet. Lots of private trackers (at least in my native tongue, but most likely in many other tongues too) that deal with local stuff. I never not found anything except some very rare cases (in which torrent, debrid or even group-FPTs didn’t help either, it was just not available at all)
As you said: if you know what you’re doing…applies to everything :)
