Hi. First I'd like to comment that I wrote that blog post literally quickly because I just wanted to convert an informal Twitter thread into a more shareable and digestible format, so I didn't take the time to make it "hackernews comment resistant" if you know what I mean.
On opinionated choices: I try to base that on mathematics. When it comes to async programming, that means equational reasoning and following some basic properties such as composition, associativity, left identity, right identity, etc, see https://github.com/fantasyland/fantasy-land . These would be neutral because math is often neutral. For instance, if intelligent aliens exist, they probably figured out the circle just like we did.
On ideological preferences: there isn't anything free of ideology, so yes I am motivated by some ideology, not unlike influential members of TC39. There, you'll often find opposition to functional programming ideas, even though JS was originally designed with influences from Scheme, and allowed functional programming better than, e.g., Java at the time. See these TC39 notes, for instance: https://github.com/tc39/tc39-notes/blob/master/es8/2017-09/s...
FP ideas are usually opposed because TC39 proposals are driven by concrete use cases, and FP is all about abstractions. FP ideology is that abstractions are good because they accomplish abstract goals, not a single particular concrete goal. That does not play well with the use-case-first process at TC39. So, ideologies.
On "it would hurt the ecosystem": I think by now a lot of people from different language communities recognize the success of RxJava/RxJS/Rx.NET, and it tackles all those complications you mentioned, but for even more complex use cases, because it handles multiple values over time. I'm not arguing that Rx is a silver bullet, I'm just saying the Rx community has first hand experience with solving and teaching solutions to the problems you mentioned in the second paragraph and it's nowhere near "catastrophic".
