What's the point of using Hitler?
I do speak German and can still follow, because in Portugal we always subtitle except for children movies, so we learn to selectively pay attention to either subtitles or audio depending on the movie and our language skills.
As far as I am aware this happens in all countries that have a subtitles culture, instead of dubbing like in Germany.
However I am also not a big fan of these clips, given the historical relationship. Not sure how much one should actually it for jokes.
Grey area for me. It's a fictional work, AFAIK, based on some evil shit in history I generally don't joke about. The scene is nearly perfect for remixes to the point many great ones have been made with it. SO, on other hand, maybe remixing his downfall in educational and entertaining ways isn't so bad after all. :)
It still seems weird to joke about Nazis.
Its similar with "Mein Kampf", Hitlers book. In Germany, the copyright ran out and it was sold again on Amazon. However now people see, how batshit crazy the guy was and what a shitty book it is. It lost most of its appeal.
As German, I say: Bring more Hitler jokes. Bring all you have.
If the meme was applied properly it would be Hitler himself who set up the Docker cluster, and the generals informing him of the ways it failed. His monologue would be about his own expectations of the greatness of Docker and how the Docker team or cgroups abstractions failed him.
The difference is subtle, but it's definitely true that in this application Hitler is not ridiculed, which makes the whole bit more awkward and less funny.
Edit: This is sarcasm.
