The author's second point (about general hostility) answered the question. The CoC comment above it appears as a non sequitur to me. You misunderstood my conclusion - it was that the remainder of the site passed my "is this a hit piece or is this just a bit spicy" check.
> The HOA analogy would be appropriate if HOAs were about conduct among colleagues.
There was nothing inappropriate about the analogy. If they both involved colleagues then the analogy would be pointless because they would be the same thing. The entire point of an analogy is the abstract similarities between things that are different.
The necessity of CoCs does not follow from the necessity of ground rules. That is a conclusion that you silently slipped in without justification. Social norms have not historically been codified as CoCs. Moreover, I would dispute that codifying social norms is the actual intended purpose of CoCs despite being the stated one.
"Very little shared interest" and "scheme to keep property values elevated" appear contradictory to me. Property values are a very strong shared interest for most people. Avoidance of noisy or otherwise disruptive neighbors are another strong shared interest. Folks just don't always agree on all the details.
> One of them addresses pragmatic and real problems, however flawed the implementation may be.
That would be HoAs, of course, which prevent my neighbor from unilaterally tanking my outrageously expensive (relative to my income) investment. CoCs in contrast are a recent trend and thus obviously unnecessary for productive collaboration.
