Tang Mingfang spent two years in prison after he shed a light on working conditions inside Foxconn factories manufacturing Amazon Echo, Echo Dot, and Kindle devices, he told The Guardian. Tang alleges he was beaten and tortured by Chinese authorities during his internment.

“I think Amazon should give me an explanation, tell me if I really deserve to be sent to jail?” Tang said. “If not, Amazon should give me an apology, along with its partner, Foxconn, to assist me to appeal for a redress, and provide compensation.”
 

Tang’s revelations included allegations that schoolchildren were forced to work long hours in the Foxconn factory, and that workers were forced to work past the allotted 36 hours of overtime in a month, with some units exceeding 100 hours a month, according to The Guardian.
