I think you have some valid criticisms of the article, but they'd probably be better received without the condescending tone. (For example, calling someone "adorable" sarcastically is guaranteed to elicit defensiveness IMO.)
Well, I think the approach taken by the author - all dolutions are known and easy and people are just stupid for not just doing the obvious - deserves it, for failing to ask - and even better, answer - the obvious question of why nobody else saw it before and fixed if if it were so easy.
