EFF Teams Up With AV Comparatives to Test Android Stalkerware Detection by Major Antivirus Apps
EFF has, for many years, raised the alarm about the proliferation of stalkerware—commercially-available apps designed to be installed covertly on another person’s device to exfiltrate data from that device without their knowledge. We’ve teamed up with the researchers at AV Comparatives to test the most popular anti-virus products for Android to see how well they detect the most popular stalkerware products in 2025

Grokipedia is the antithesis of everything that makes Wikipedia good, useful, and human. Grokipedia looks like what you would get if you told an LLM to go make an anti-woke encyclopedia, which is essentially exactly what Elon Musk did.

Grokipedia Is the Antithesis of Everything That Makes Wikipedia Good, Useful, and Human
Grokipedia is not a 'Wikipedia competitor.' It is a fully robotic regurgitation machine designed to protect the ego of the world’s wealthiest man.
