I am having a hard time understanding how things like Project Gutenberg content could be deemed terrorist content.
Techdirt article is a bit more readable to me. A little bit more verbose. And provides some examples on how these flase positives are being triggered.
Those are the requests from Europol, who unfortunately likely qualify as a “competent” authority under the law. The Archive also points out the request from both Europol and the French computer crimes unit targeting a page providing commentary on the Quran as being terrorist content. The French agency told the Archive it needed to take down that content within 24 hours or the Archive may get blocked in France.
