Germany has agreed to stop ChatControl for now, due to huge amounts of public pressure. Good job! The bad news is that it could come back as soon as December, and the German government has interpreted the feedback as a need to “moderate” the proposal.

Discord user IDs getting leaked is the entirely predictable consequence of requiring platforms to do age verification. That data never goes away, it spreads. In this case, into appeals in a breached customer support database. And predictably, it can get worse. www.404media.co/the-discord-...

Someone please make me understand how Denmark can be at the same time freaking out about hybrid war with Russia AND pushing for government-mandated spyware as Chat Control.

More than 500 researchers have signed an open letter against the dangerous EU proposal on chat control.
The proposal remains ineffective, undoes decades of results in E2E encryption, and threatens the privacy of half a billion citizens.

The EU Parliament has published a new proposal for Chat Control to mass-surveil all digital communication in Europe. The proposal is ineffective, weakens secure communication, and violates basic human privacy. This must be stopped immediately. #ChatControl

EU is demanding that every site use age verification technology, while insisting it do things it cannot do, and behave in a manner it cannot behave. This is not policy making. This is wishful thinking, with a side of "we'll just blame the tech companies for not waving their magic wand."

The problem with most machine-based random number generators is that they’re not TRULY random, so if you need genuine randomness it is sometimes necessary to link your code to an external random process like a physical noise source or the current rate of US tariffs on a given country.
