I don’t believe it’s so much about the correction itself as it is about ignoring what the person said and only piping up to correct. Imagine we are having a conversation and you spend 3 minutes telling me about how you struggled to get the lug nuts off your tire this morning while changing it and when you finished, all I had to offer you is “they’re on the rim, not the tire” and nothing more. It can come off as a bit rude.
That’s fair, but it’s hard to not bring up servers when someone is making broad statements like “businesses don’t use Linux”, though. In the scope of that particular discussion I feel servers are pertinent enough.
