It appears that Ars Technica is not very technical, or up-to-date on tech. Today's "LimeWire" is just a basic centralized WeTransfer-like file transfer service, with a crypto NFT token attached. Real LimeWire, the P2P Gnutella client, has long been dead. Old versions can't connect anymore, probably due to bootstrap servers being offline.
But this entire article is based on Reddit, so that very much explains it.
No? The entire first part of the article is about the decision to kill/delay the episode, which has been widely reported on. The LimeWire-specific stuff only comes fairly far down
The entire important part of the article, i.e. the headline and why it is something that Ars would be reporting on.
Your objection is silly. They're not reporting on that thing that everybody knows about, they don't know anything special about, and is not part of their beat. Instead they're copying from reddit, badly.
edit: I've gone through the article, and I guess I'm dumb. They're using a Reddit thread as an excuse to recount a story that they have no part in and no expertise to report on. A fake Limewire story is supplying the linkbait of an excuse for a tech website to do a "Trump bad" story. Ars is fully owned by Condé Nast.
They didn't know it wasn't Limewire because they didn't give a shit about the Limewire part.
