I honestly fail to see the larger point of that legislation, if a platform is as clearly targeted towards the crimes specified in the proposal it should already be covered by a plethora of German and EU wide law.
Alas a small word on the legislative procedure. This is "only" a draft of a proposal of the Bundesrat (what in most states is called the Senate). The 'Bundesrat' has no legislative authority, so in essence this is a paper that 'calls the Bundestag (House of representatives)' to initiate a legislative procedure -- on itself it is pretty meaningless but has the chance to become a problem.
The chance is pretty good, given their recent track record.
the problem with wide legislation is that it's got a chilling effect.
Would bitcoin or crypto currency be targeted? it's a fully anonmyous payment system which could circumvent anti-money laundering laws, and be used to conduct illegal activities.
I think platforms should never be charged as illegal. Only acts that are illegal should be charged, and the platform where it takes place should be deemed a neutral utility or carrier.
Who knows what's going to be illegal tomorrow? Who knows if a fascist gov't comes into power, and starts targeting specific groups, using such laws?
Is the purpose of this infrastructure to facilitate all this criminality? Certainly not the sole purpose. Perhaps it was purposely build in a way that would allow scale and prevent censorship which enables many forms of criminality which a different architecture would have suppressed.
Typically the law is written quite differently. If there is a uncoincidental legal purpose, then infrastructure must be legal. Because many times the purpose of a specific technical measure can serve both a legal purpose and a criminal one. To ask merely of a technical measure serves a criminal purpose without regard to a greater purpose is to criminalize any censorship resistant network.
There's two vastly different talking points here, a) the Tor network and similar tech that could get caught in legalese crossfire and b) specific websites that utilize the above. I agree on your sentiment that a) should never be outlawed but the German text seems rather specifically worded to address b). Please be assured that I'm not trying arguing that these people have enough technical understanding to not make it unnecessarily broad and throw a) under the bus as well.
I believe my main point still stands, b) is the equivalent of me opening a corner shop advertised as "illegal arms deals" and pretty much legislated enough.
Based on my understanding of Czech law (which is alike German law, but not that much), the point lies in process issues. Having specific laws allows the government (meaning the executive branch) to form law enforcement units, establish government offices dedicated to the issue etc.
