Forget other EU countries and laws, the German constitution guarantees private postal and remote communications for every citizen. It’s also why Germany has historically never (that I know of) voted in favor of this bullshit: it violates the Briefgeheimnis (article 10 of the German constitution)
If they hadn’t rejected it the federal constitutional court in Karlsruhe would have sacked every single proposal on how to implement it, a process our current coalition is very familiar with from multiple attempts at trying to push preemptive collection of unencrypted data. They knew it wouldn’t pass here anyway and likely just waited on an opportune time to profit off the inevitable denial. Although I’ll give them that: some parts of the coalition were rather eager to meet the judges in Karlsruhe again anyway so it wasn’t a 100% guaranteed rejection either.

Guarantees secret postal- and remote (original intent: radio) communications which applies to the internet ever since they thought they could make a quick buck by demanding radio broadcasting fees from youtubers, by which they placed the entire internet in the domain of radio laws.
