I don’t think it’s helpful to flag things people disagree with, as long as they don’t attempt to spread misinformation, or trolling etc. The parent phrased the topic as a question, meaning I believe they were open to understanding.
I also think it’s relative to the topic posted, as we’re talking about either an attack on archive.org, or a massive recopying of archive data by an unknown.
Talking to people with opposing views is important. Let’s not just shut people down if we don’t agree with something, especially when someone is asking a question.
