Facebook, YouTube and Zoom are facing accusations of censorship after the platforms blocked the streaming of an online seminar at San Francisco State University featuring Palestinian activist Leila Khaled. Zoom and Facebook blocked organizers from using their platforms in advance, after coming under pressure from groups including the Anti-Defamation League and the Lawfare Project. The start of the seminar was live-streamed on YouTube but then was abruptly stopped after 22 minutes. In other tech news, environmental and Indigenous activists recently had their Facebook accounts temporarily suspended as they planned an online protest against private equity firm KKR, an investor in the Coastal GasLink pipeline in British Columbia.
