I bet nobody from VW is going to know this exists for a year or more, if ever. How many VW corporate employees do you think browse HN?
Out of more than 600'000? A bunch, I bet.
(Yes, I was shocked at the number too)
It's also worth saying that even if they don't have a automated system to look for x-infringement, they have many employees who when bored could end up searching for (say) Volkswagen on github.
Whether they care or not is another matter...
