The explanation is deceptively unclear, IMO. What's being authorized is
court-ordered searches of a type that were previously prohibited, even for courts to authorize, by strict privacy laws. The US has always had the power to conduct these searches [0]; the "inviolability of the home" human dignity concept doesn't exist in the US. (I'll defer to German people to explain this concept).
As explained in heise.de[1] (in German) about a parallel law being enacted in the state of Mecklenburg-Vorpommern,
> "For the online search, the deputies now also grant the law enforcement the right to secretly enter and search apartments with judicial permission."
