My best guess is that they just leaned into that scraping mindset, that I already disliked ten years ago when batches of zine covers from fanzine sellers just got uploaded. I think they hope somebody will eventually rework things into articles using scraped bits as scaffolding? But it's a kind of underwear gnome type of mechanism as for how that's supposed to materialize. And from the looks of it, the wiki committee and policy development is as opaque as ever.
