Where does he make fun of JS devs? Call them idiots? Morons? You're overreacting in a big way. Almost everything he points out is a totally legitimate criticism of the language, not the people who use it, and he does so in a good-natured way. Everybody knows we don't just pick the language we think is "best". Far from it. And on a side note, appealing to how widespread it is seems obviously faulty - I think you probably know how little relationship there often is between usage and quality due to the nature of the software ecosystem.
