Yes, it does need to be said. Many people will read this article and miss the satire, which is, in part, the intent of sophisticated satire. The point is that it is outlandish and foolish and ridiculous and yet still resembles some serious discourse that real people engage in. So much so that some onlookers can't tell the difference. That proves the satirist's thesis: the real world is full of ridiculous people making ridiculous arguments and they can't even see themselves or their arguments for what they are.

I know real life people who write essays with claims as outlandish as "software engineering is an ableist field" and are dead serious. But that assertion belongs just as well in a satire piece. It can be very hard to tell if you don't have prior context for the author.
