The NetzDG is bad law, and will probably be repealed before the Constitution Court rules it unconstitutional.
But it was a reaction to social networks disobeying the law. An overreaction, yes, but a reaction.
I wish it were more commonly known in libertarian and net freedom circles that the pendulum swings both ways. After excesses in one direction it will swing far into the other direction.
Maybe keep that in mind when pursuing extreme goals at any cost, instead of find8ng a middle way that works for everyone.
I think the NetzDG is crap and won‘t stay for long. But I also think that Facebook and Twitter deserve all this pain.
