I think there are a lot more younger inexperienced people trying various types of polyamory. Probably leads to a lot of mistakes and bad taste in people's mouths... I've found that most people under 25 don't really know what they want. I've also noticed that younger generations tend to be partnered super early in school and don't really know how to be alone. Even to the point of taking fake relationships just because that's what everyone else is doing.

There are always gonna be shitty people, monogamy or no. Some people take advantage of polyamory as an excuse to ignore ethical responsibility. I always preface that I practice relationship anarchy that looks a lot like ethical polyamory (even though polyamory is already supposed to be ENM).

People seem to think that polyamorous people are always available. One of my partners has this problem but I personally enjoy watching them rip ignorant people a new asshole.
