Not really. Take the current position of Facebook. Assume Facebook was around in 1930. Now answer, would Facebook block nazi propaganda?

Judging from another American tech company that faced the same challenge, one could argue they would not block. https://en.wikipedia.org/wiki/IBM_during_World_War_II and https://en.wikipedia.org/wiki/IBM_and_the_Holocaust

Propoganda? No. Outright ads on the final solution? Probably yes, but also bear in mind the Nazis weren't exactly broadcasting their plans to the outside world. (At least I don't think they were - am I wrong on this point?)

its discussed in limits on that wiki page

>An invocation of Hitler or Nazism is not a reductio ad Hitlerum when it illuminates the argument instead of causing distraction from it

The fact that this is coming from a man whose people were actually in history targeted by Hitler himself gives weight to what he is saying.
