The comments section got absolutely slaughtered by Reddit and 4chan after this made its way on a popular subreddit.
That said, I personally thought her entry only ended up (unintentionally?) conforming to the very stereotypes the project served to satirize in the first place.
I agree with you that her entry unintentionally ends up skewering itself by running head-first into the joke. Really though, she skewered herself by ranting about a really bad joke.
The C+= joke sucks. It's poorly executed. It's far too self-conscious and has way too many "wink-wink" moments to be effective satire. You either need to be clever and subtle, or absurd and outrageous. Instead, most of the jokes fell flaccidly in the middle: too obvious about its subject matter, but not even remotely clever. Making it a programming language doesn't make it clever joke, it just means you tried really hard to tell a joke.
And she fell for it. Which ironically validates its existence, poor joke execution be damned.
