Avoidants and polyamory

Has anyone else found that some people use polyamory as a way to avoid real intimacy / boredom/ conflict? Like, oh this partner is expecting me to be consistent, own my actions, have difficult conversations, I'll escape to someone else.

I personally expect all my relationships to be real and include hard conversations and addressing feelings, but sometimes it feels like the people I meet just want a fairweather girlfriend to escape their problems with.
