There was nothing deliberate about it. I wrote the headline before I wrote the rest of it, and clearly my initial understanding-at-a-glance of the situation was wrong. Then I wrote the rest of it, followed some sources, and tried to provide as much truth as I could.
What happened next was — I kid you not — my toddler woke up early from his nap. So I finished typing and went to take care of him. I ended up submitting the blog without revisiting the headline.
So yes, I fucked up. But good luck proving any conscious or intentional deceit.
