Any intuition on why this sentiment is so strong on HN? I find it quite puzzling.

Tesla and Bitcoin generate hate since they both have somewhat of a cultish following (whether that's good or bad is a separate topic)

I wouldn't put JS in the same category.

Sure. But if one doesn’t like cults, why join a counter cult? “Tesla can do no wrong” and “Tesla is pure hype” are pretty much the same in that they are excuses for not seeing, thinking and judging.

I mean, I can kind of understand the javascript thing as there are lots of great developers here and it can be frustrating when there are "better" languages that don't get any love.

The Elon Musk / Tesla / Bitcoin thing I don't understand. Anytime there is a link on HN about these, I know it's going to be a "See, I told you so" type of link where they try to justify their hate.

Perhaps it's because Elon Musk is the best "startup" guy and there is jealousy? I don't know. It doesn't make much sense to me.

Bitcoin has elements of environment destroying ponzi scheme that can be a legit complaint against it.
