Against ‘chat control’: we can’t eliminate child abuse by eliminating privacy

The entire bottom 50% of America is worth just $4.2 trillion.
Read that back.
When 400 people control more wealth than half a country’s population, we have a very serious problem.
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.

<<“brain gain” is exactly what we have experienced. As Danish companies have succeeded globally, they have sought out the best and brightest in their respective fields from across the world. The number of foreign workers in Copenhagen has more than doubled in the last decade.>> @madshvid.bsky.social

Good news: There is still time to fight back!"

I know it’s been said again and again, but what does it say about ChatControl that its backers keep explicitly *exempting* law enforcement and national security accounts from content scanning?

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

The EU wants to spend your money to assemble a giant mass surveillance machine with little effect on harm against children. Chat Control is not effective, weakens security for all and does not respect privacy. Contact your EU representatives and let them know.
csa-scientist-open-letter.org/Sep2025
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.

It was too late when I figured out this was not about cryptography.

Até porque quem está decidindo sobre a implantação são os próprios governos, que nunca vão admitir poderem ser maliciosos. De qualquer forma, nem a versão honesta funciona porque a taxa de falsos positivos é proibitiva.
