The PDF has a four sentence summary. The lazy critic did not quite reach the second sentence, which literally prohibits a selection of planes from landing on some airstrips due to a dangerous software bug (the details of the bug, which airstrips, and sort of why, is in the rest of the article — but it's pretty clear the lazy critic didn't make it past the post here).

If they'd read the whole PDF, they might have seen these bits:

"All six display units (DUs) blanked with a selected instrument approach to a runway with a 270-degree true heading, and all six DUs stayed blank until a different runway was selected."

And:

"An unsafe condition exists that requires the immediate adoption of this AD without providing an opportunity for public comments prior to adoption."

That's pretty serious, and indeed fits exactly with "some Boeing 737s can't land due West."
