I think it's a combination of quality issues and distaste with some of their business practices. I don't really have a dog in the fight (aside from just generally not liking large corporations), as I'm not really up on their history and far from an expert on all the issues involved. I started my modular journey with 4 neutrons which I still own and use to some degree, they are great bang for the buck and a great way to get started in modular IMO. But I've never tried any of their eurorack modules, and haven't read particularly great things about them. I imagine some of them are probably good value, while some of them probably suck haha.
