All of the big file hosting platforms have long had copyright and child porn content filters. The fact that they are policing ToS violations (presumably only after they are reported or scripting re-violations) doesn't seem anywhere near 1984-style censorship.

I do fear that this will give the tin foil hats more conviction that "there's something to it since they are hiding it!" and not more motivation to be skeptical of this particular thread of inquiry about the pandemic.
