At CrowdMedia.co, we only allow editorial use for 2 reasons. You need model release for commercial use (from any recognizable person, brand, design, building), and a lot of photographers just don't want their photos in an ad for a company with what they consider wrong corporate values.
Non-commercial, as in "not related to making money," has never been well-defined and Creative Commons has consistently punted on this topic. Their last attempt to define it has been languishing for a good 5 years now. The problem is that if you eliminate all uses that encroach on money--e.g. an ostensibly personal blog that is related to my professional business in some way--you're left with uses that are essentially trivial. And, by the way, it doesn't really matter if there's no meeting of the minds about what constitutes commercial use and there probably won't be.
