The problem starts if the state wants to save money and skills in intelligence to work around common challenges of anonymous services. The real criminals attacking the constitution often can invest time and money into unbreakable anonymization, such things mostly hinder easy access to privacy by the normal citizen like me. The german government has really a long record of distrusting anonymization starting with ISDN mixes and denouncing their users. But also little things like one time credit cards seem to be restricted only because it would take an extra step to link the data in a real criminal case. And regarding data protection: it was big on paper in germany for a long time but only because nearly nobody was actually sued. Now everyone shits their pants here about the GDPR because you at least there are fines ( the rules did not change much). At the same time even with the GDPR we only trusted other german corps with data as corrupt or leaky they may be and not other Europeans. I agree with the OP that there are double standards here. But mostly it is just a history great theoretical ethics combined with technical incompetence and the deep national feeling of moral superiority...
