Nor do they need to. 99% of everything is crap, and not worth prescribing except for a random sample so future historians can study our crap.
Torrent/P2P can only add redundancy, so it’s impossible to have worse availability than a download link?
That said, for large files, I much prefer the UX of a well-designed torrent client like Transmission to my web browser. If nothing else, the downloads are reliably resumable.
Brave browser had BitTorrent client built in for a while. I tried it a couple of times as I already use Brave for web browsing on my laptop. It was a very confusing BitTorrent client. I struggled to use it, and wasted time waiting for a download to complete only to not be able to find where the files were and then they disappeared. Using a decent BitTorrent client like you say is much preferable to the one that they had in Brave browser.
Opera did back in the day.
