in June the Hannover Regional Court had struck down a lower district court's ruling that Tutanota was to be backdoored. While angry police workers reportedly threatened to attack Pfau, sending him menacing emails promising to abduct him from his home and throw him into "provisional detention" unless he obeyed their orders, the regional court dismissed the district court's ruling – leaving police powerless to follow through. Tutanota's successful legal argument at the time was that it did not qualify as a "provider of telecommunications services" within EU law. Pfau explained to
The Register how the German police were attempting to counter that: "Although we are no longer a provider of telecommunications services, [they say] we would be involved in providing telecommunications services and must therefore still enable telecommunications and traffic data collection." He added: "From our point of view – and German law experts agree with us – this is absurd."
In September, not long after Pfau's personal battles with police,
unidentified persons launched a series of DDoS attacks against Tutanota.
