Hong Kong/San Francisco (CNN Business) A US-based group supporting human rights in China says it is "outraged" that the video conferencing company Zoom ( ZM ) temporarily shut down its account after it held an event on the platform in remembrance of the Tiananmen Square massacre . The group said more than 250 people worldwide joined the Zoom conference, while others streamed it on social media. "The Zoom account used for this conference displayed a message that it had been shut down," the organization said. On June 4, 1989 , Chinese troops entered Tiananmen Square in Beijing and fired on civilians protesting for democracy after several weeks of demonstrations. In its statement, the group accused Zoom of being "complicit in erasing the memories of the Tiananmen Massacre in collaboration with an authoritarian government."
