How many people get divorced? 1/3 of the total, right? So, around 33%. What's 2% of 33%? Less than 1%. Even if we round up to 1% here, and estimate that 6% of the population have open marriages, then this would mean that 1 in 6 open marriages end up in divorce as a result of this marriage being open. That's 17%, which fares rather favorably with the general 33% divorce rate. Even if some people in open marriages divorce for other reasons, it's entirely possible that on the net, the divorce rates for people in open marriages would be comparable to the divorce rates for people in closed marriages. And if this is indeed the case, then there is sound logic behind this: Specifically assortative mating. People often choose compatible traits in their marriage partners, which in turn makes it easier for them to get along as married couples. This applies to polyamory just as well as it applies to various other traits, such as people who love fat people marrying fat people. Obviously sometimes people have their expectations disappointed, but that's true in general, not just for polyamorous marriages.
@History Learner Did you ever take a look at this post of mine?
Anyway, FWIW, I see it like this: We have tried forcing monogamy onto people for centuries or more and in a lot of cases it didn't work out, with cheating and betrayal and hurt feelings and whatnot. Why not try giving people who are wired to engage in polyamory a different model to work with?

No relationship model would be absolutely perfect and flawless, of course, but a model that results in less hurt feelings and less betrayal seems like a better model, don't you think? At least polyamorous people would be honest up-front about what they want with their partners from the very beginning rather than trying to make an arrangement that might not work for one or both parties. It's one thing to voluntarily enter a polyamorous marriage from the very beginning and another thing to try opening up a marriage later on; the latter can work, but it might also be riskier.
Personally, I myself really like polyamory since I don't want to limit myself in regards to sexual partners any more than I want to limit myself in regards to food varieties. And since I'm especially attracted to women who are capable of ovulating, I will definitely need to engage in polyamory in any case after my future wife will hit menopause. Yes, seriously. She can also find her own lovers, of course, just so long as she'll also be sterilized.
