A wave of protest has hit Meta's London headquarters today as authors and publishing professionals gather to voice their outrage over the tech giant's reported use of pirated books to develop AI tools.

Among the protesters are acclaimed novelists Kate Mosse and Tracy Chevalier and poet Daljit Nagra, who assembled in Granary Square near Meta's King's Cross office to deliver a complaint letter from the Society of Authors (SoA).

Still, the damage to trust within the creative community appears significant. Author AJ West, who discovered his novels were listed on LibGen, described the experience as a personal violation:

'I was horrified to see that my novels were on the LibGen database, and I'm disgusted by the government's silence on the matter,'he said, adding,'To have my beautiful books ripped off like this without my permission and without a penny of compensation then fed to the AI monster feels like I've been mugged.'

Legal action is already underway in the US, where a group of high-profile writers, including Ta-Nehisi Coates, Junot D
