Please don't compare. I don't give a damn about certificates, and I think it's totally fair for them to be paid. Actually, as I think it's only normal to not give a damn about certificates, I'd say even some kind of "full track" with exams is ok to be paid for. They still provide good learning material for free. And, by the way, the quality of the course material on edx is arguably better. It's a shame that coursera's got way more recognition somehow, apparently.
