I'm starting to feel some sorta way about open-core model as more of a marketing mechanism for lead gen. I can't put my finger on it and I'm not saying it's bad. It just kind of feels like it's like a free-trial that appeals to engineers, that helps jumpstart your marketing funnel top-end.
I'd love to hear Richard Stallman rant about this...he'd probably find a way to articulate, more elegantly, what I'm feeling.
