I don't consider "lacking" to have that implication. Especially not in the context of the Oxford comma, as lack of an Oxford comma is well known to be a source of ambiguity(1).

As the article illustrates, our languages are full of ambiguities. Human communication is limited in bandwidth and which features are preserved when we use lossy compression to shrink an article to a summary or title depends on priorities. For example, your suggestion:
> Legislators drafted ambiguous statute and company's interpretation lost out
emphasizes who is at fault, business or government, but loses what the dispute was (overtime pay), where the case was located (Maine), why there was ambiguity (the Oxford comma or lack thereof), and how much was at stake (millions of dollars). There's also something to be said about making it sound catchy (like the alliteration with "Maine" and "millions").
You could put all that back in, of course, but at the cost of more bandwidth consumption. And since everyone has different priorities (for example, someone else might want to know that the company was in the dairy business), there's always more to add until we reach the point where we're just reading the entire article.
So yeah, that's a good insight, but the top HN comment shouldn't be that the article's headline could be interpreted differently.
Good points, and thanks for your thoughtfulness. I agree that "misleading" could be a tad too emphatic, and I'd be open to other descriptors that might be more accurate.
When you read the article, you see that the comma is not from a company document, but from a statute. So the "lack" is due to legislative drafting. But reading just the headline, how could one have imagined that the "lack" was due to an unnamed actor that drafted an unnamed statute?
While the implication I described is not the clearest implication, there is no way a reader could see this headline and have any clue that what really happened was:
Legislators drafted ambiguous statute and company's interpretation lost out
But that would make for a lousy headline, I suppose.
