Twitter, if it wants to continue operating in Germany without facing lawsuits / prosecution, has to bow to German law.
It would be better if they could just reliably block the account from reaching German users only, while other users would continue reading the tweets. It, of course, is impossible unless Germany implements a country-wide firewall, the way China did.
I don't think it's likely, though. The point of actions like this is not to strictly eliminate any last vestige of hate speech. It is to send a message, so that other would-be-satirists could reconsider starting an account that breaks the law, and that other international companies which deal with UGC knew what to expect, and took preventive measures.
Which they are not forced to do as there is no such law that binds foreign companies that would apply to those subreddits. They preemptively blocked it completely after they received a letter with some questions by a German government agency that was thinking about including a subreddit into an official block list used by (voluntary to use) youth-protection software or Google. Even if it had been included in the list, it would have been accessible from Germany.
