For a Chinese "security" executive at Zoom, "security" meant the security of the Chinese regime. He reported on users to China, and snooped on meetings. If they discussed the Tien An Men Square massacre, he terminated the meetings and the participants' accounts, on the orders of China.

Zoom management responded to the scandal by promising that in the future Zoom would only cancel an account on China's command this way if the user is in China.

Other companies that help the Chinese government impose repression include Apple and Google.

Can we expect a big company to have the scruples to decline the invitation to gain access to the "Chinese market" by becoming part of the system of oppression?

No, we can't expect it. But we must demand it.

This was the work of a rogue employee, but what made it possible is that Zoom's design lets staff snoop on every conversation as it passes through the server without getting a search warrant.
