Unfortunately the culture I’ve experienced in the past few years has been essentially that, but for anything that does not use a common npm library. “Why is this not done with React/Vue/Typescript/Angular/<insert favorite thing here>?” is a question that’s posed less as a question and more as a condescension in many cases. The rebuttal “because not using XYZ works just fine” is not often accepted, true as it may be, followed by bashing the non believer in question into submission.

I’m with you though, I don’t think the bashing is necessary, in either direction. It just breeds contempt.
