Looks programmatically generated. The whole account is the same style of incoherent nonsense. Probably powered by https://en.wikipedia.org/wiki/GPT-3
There's a few other accounts I've seen here on HN that just spout random incoherent nonsense text, presumably to accumulate karma so they can power their sockpuppet ring and upvote any story they wish to the frontpage of HN.
Seriously though, that sentence contains a lot of relevant context and understanding that would rival LaMDA. :)

FWIW: Greenwald, as odd as his recent flip to Q-adjacency has been, doesn't seem to have been involved with the Winner episode.
It seems like Winner got burned as a source by a plain old journalist who fucked up badly while making a good faith attempt to validate a story. They got a bunch of scanned documents purporting to be from the NSA, so they called up the NSA to see if these documents were real. And in the process they provided the original scans, which identified the source printer and user.
But no, Glen Greenwald didn't have anything to do with this.
Reality really chose the correspondent for her leak unwisely.
