>I think the author is missing an important point: people who are genuinely curious about Holocaust usually don't type "did the holocaust happen"

This seems to make a big assumption about what defines "people who are genuinely curious". I think your queries of "holocaust statistics", "holocaust wikipedia", etc would instead describe someone who genuinely knows how to critically think and search for information, as opposed to someone who is simply "curious". You or I would search for info in that way, but a curious person could be anyone (e.g. a child or a teenager who has just been told by a peer that the holocaust was a hoax). Their first instinct might not be to search for specific sources or statistics, but rather to type "did the holocaust happen".
