Not sure if scolded is the right word (non-native speaker), but I think "False" as an answer to an rethorical question is only worth much if the point you are making after the false is one that is really obviously false.

If it is false only if you pinch hard and look from the right angle it comes of as "Oh come on, you just don't want me to get this right" — which in this case runs counter to the whole idea of the blog post as I understood it.

I had a teacher once who was like that: whenever someone he didn't like got something wrong he would pull out some pedantic detail to still make it look like the person was false, even though they really really were not. I kinda think this is just a little bit unproductive in an educational context.
