"At the same time, we're addressing risks posed by crypto and the anonymity it enables."
Wherever their headquarters is located doesn't matter, but what is worrying for bitcoiners is how institutions like this attack BTC privacy solutions, as you can see from this snippet above. BTC is just a tool, surely Satoshi never created it to be used for illicit tx's, but any tool in the world can be used both for good and bad. However, i don't think there is a 'threatening' number of people using BTC for money laundering, it has a public and transparent blockchain and is not anonymous, but they still attack BTC like it is the most suitable tool for money launderers.
Indeed, it does not matter where their headquarters are located. The important thing is that they agreed to form the new European authority for anti-money laundering and countering terrorist financing, and this is what is important in the news, not the location of the headquarters.
But on the other hand, as @zasad mentioned, choosing the headquarters in Germany indicates their seriousness because Germany is an influential member of the European Union and has great economic and political importance.
Also, after its formation, European Authority will have the right to intervene in all countries of the European Union regarding Bitcoin and cryptocurrencies, even those countries where there are lenient laws regarding Bitcoin and cryptocurrencies.
