The original site that the post was on has been taken down, but here's a pastebin of the relevant text (posted with the consent of the original author, one paragraph removed to preserve the author's privacy). I should add that my own view of poly is considerably more negative than that of this author, but even the linked post is significantly more negative than the Bay Area rationalist community norms tend to be.
Also, I slightly worry that what you're seeing is skewed because the kind of people who are willing to try polyamory are unusually open about their personal lives. That is, I think there's a lot of drama going on with monogamy, too, and it just happens that people who choose to be monogamous also have a culture that better keeps drama secret until it is too big to keep secret anymore, so it simply looks more common in polyamory because it is less hidden.
I think that there is certainly a lot of drama with monogamy as well, and I agree that some aspects of this can be under the surface. That being said, I think there are some aspects of poly that tend to exacerbate/lead to drama while there are some aspects of monogamy that tend to mitigate/avoid it.
I'll give a basic example. Let's say that there is a couple in a committed relationship, and one member of the couple starts getting closer to a third party. They become more and more emotionally close until eventually this bond seems stronger than the original relationship and the original couple splits up.
Now, this could easily happen either in monogamy or in polyamory -- you could say that it's the story of an "emotional affair" that turns into a real affair and splits up a monogamous couple; you could also say that it's the story of a secondary relationship in a polyamorous situation that turns into a primary relationship and splits up an old primary relationship. In point of fact I have seen cases that seem to fit this description in both monogamous and polyamorous situations.
The key difference, though, is that monogamous norms tend to work against such things, while polyamorous norms tend to encourage and even directly support such things (until perhaps things go too far and it may be too late). The person who starts to form a close bond with someone already in an established monogamous relationship may be chided or discouraged by the community; the person who starts to form a close bond with someone already in an established polyamorous primary relationship is less likely to be chided and may even be supported.
In some cases I believe I have seen this lead to major strife or even divorce in a way that I suspect people would have disendorsed and tried to avoid if they were better equipped to predict; unfortunately, they were dealing with polyamory norms that made them extra vulnerable to this sort of thing.
