Does it matter if he said curd or cheese? Yes, he's correct if jorb has stated clearly as to why this is. You're just being pedantic.
If anything, make an argument as to why it should be changed. Something like "It's weird as hell, I think, and something I always forget. Not sure how many times people have asked this world what they were missing for recipes to make cheese processing parts--trays, rennet, etc. Such details aren't easy to recall so the posts don't get answered in a timely manner." To which I might answer: "Perfect details to go into the wiki. If only the two people having the discussion were wiki editors..."
The dev comments about "community knowledge" like the wiki are out there. That said, maybe such things should be a bit more obvious. It's not like a person just didn't learn it. Usually they're trying to teach an alt or just skipping ahead a step or two, which can be amazingly simple to do if you don't know the steps.
