arXiv? I mean, you're looking at preprints, and you might have a higher dross-to-gold ratio, but can't you do your research there, without the moral dilemma?
It's not even close to an alternative.
I don't do research, but from my point of view the issue is pretty much settled, there's no reason to doubt. Current publisher are just plain wrong and don't deserve people to feel bad over them.
