> For Wikipedia itself: The “reliable sources” policy needs to grapple with a new world where LLM assisted vandalism can produce plausible press releases at the click of a button. Citation only to a single source registered within an edit window is a discoverable pattern for Wikipedia as well.

A press release isn't a reliable source per Wikipedia policy already. The edit should have been reverted based on inadequate sourcing even before the blog post. The reason this wasn't done is simply that not every article is checker for adequate sourcing all the time.
