I don't know why you have been down-voted, but you're somehow right. In American English it is common to put month before the day. An URL in the submission contains locale "en-us". If you would switch the localization of the website, let's say to German (de-de), you will see "9.1.2022". Give a try in other languages:

>It's an American company so it's really not ambiguous

I don't think that necessarily follows. ~4% of the world population is American so it's likely that a sizable chunk of the website traffic expects the non-US date format.
