German court upholds its ban on comedian's Erdogan poem
Not the exact same business situation, but is that an example? Guy can't make a living off of his comedy because he's mocking a dictator.
I've actually met ex-nazis in Germany and I don't believe the causality you're proposing holds up.
Yes, neo-nazis think the "jews" are running the country and keeping them down, but this is no different from how the antifa think the "fascists" are doing the same.
The recent rise of nationalism in Germany actually has more to do with both major parties having become indistinguishable in many cases and "moderates" flocking to the extremes to "punish" the government.
It's a lot like trolls on 4chan spreading racist memes "for the lulz" until they end up having become actual white supremacists participating in Nazi rallies instead of merely shitposting on the Internet.
Right-leaning "moderates" vote for the right-wing extremists (NPD if you're really angry or AfD if you are more of a realist) out of spite and then fall for the rhetoric as they continue exposing themselves to their messages.
The only effective treatment against this disease seems to be constant exposure to other people with other ideas coming from other walks of life.
Yes, there's an East/West divide in neo-Nazi density in Germany, but it's also very much a rural/metropolitan divide. If all the people around you look, talk and think like you, everything different becomes a threat to your way of life.
The whole purpose of the poem was to get banned.
Mr Boehmermann's lawyer said the ruling went against "artistic freedom".
"We believe that the court's decision in its concrete form is wrong, given that it deems those parts dealing with Erdogan's approach to freedom of expression to be acceptable," said Christian Schertz.

He's also still very much able to "make a living off of his comedy". His "Schmähkritik" (the title of the piece as well as the crime reciting the poem would constitute) was just a single one-off performance on a publicly funded TV show.
