There are people online who are wrong. I can’t just ignore that, they must be told why they are wrong.

Seriously though it’s a good idea to correct people when they make stupid baseless claims because other people won’t necessarily have the technical understanding to judge whether their claims are based on reality or not.

Many of the people who are doing this are YouTube or Instagram personalities with lots of children following them, I like this product and want it to succeed, and I don’t want children to lose interest in the idea because their favourite idiot instagrammer reckons it’ll cost an absurd amount of money.

I’m utterly confused about why you are upset that people are doing that. There’s absolutely no need for you to engage in it.
