Who decides what stays up: Zuckerberg, Wales and Hotz on pressure and control

Mark Zuckerberg and Jimmy Wales describe how Meta and Wikipedia respond when governments push on content and data, and their answers differ because one runs a company with staff and servers and the other a volunteer project with no advertisers.
