I'm not so sure that I agree with your perception of the tone. The high-level takeaway I got from this article with respect to C was, "C's abstract machine is clearly the best way to think about performance sensitive programming, but the type system sucks". Is that not a fair statement? I suppose there was an intro bit about Rust's lack of advertisement as a functional language (and perhaps that comes off as snooty), but from what I've seen of programmers outside of HN, this is a reasonable precaution. Most others I've talked to are either simultaneously ignorant and apathetic towards FP or actively distrustful. I literally had a friend at a major tech company tell me that he avoids FP because he does "real work", and he shouldn't have to bother with "idiots and their lambdas". Then again, everyone likes to feel like the downtrodden victim. Dropping the pretense on both sides and trying to elucidate without proselytizing is the most effective strategy.
