Not a lawyer or anything close, but I think Volkswagen is a trademark, and when used in a way that makes fun of them, you are likely to wake up their dogs (legal team) from their sleep.
Unfortunately, whether they profited or not won't make a difference. Just from the individual HN comments alone, there is enough to suggest that the title easily creates the notion that it is Volkswagen that has authorized this github. In fact, until I spent more time reading the comments and the github repo page, did I realize it was not actually Volkswagen but an individual.
Basically, if you publish on a platform that is being used by other large corporate brands, you should more or less expect zero legal protection from the platform as ToS is not a legally binding contract.
