I think your examples aren't that much censorship but rather individuals/politicians asserting their rights not to let anybody smear them on social media.
The rules which made e.g. insults illegal haven't changed but society stopped allowing anonymous people online getting away with it.
Maybe some background for non-German readers on Pimmelgate (Dick gate):
Pimmelgate happened when a secretary of state in one of the German states was called a 'dick' on social media and the politician had the guy who posted this swatted by state police. The state minister lost the resulting legal battle and was ridiculed online for his short fuse.
Not pretty certainly. Certainly an abuse of power by a politician leading the police in that state, but also widely reported and criticized. In my mind it doesn't compare for instance Donald Trump going after Comey or suing public broadcasters.
