What you describe is that paying customers subsidize 'community resources', which is great for me as a mooching Rails (and github) user, but perhaps not so great for paying customers. I don't think they'd put it that way; and indeed I believe they must provide a lot of 'extras' for their customers for the cost of that service. Still though, it seems that it's a service that will be best with clients who make a lot of help requests, getting their money's worth.
