If they did you can bet that the new, combined cost of all of the features would be far in excess of the few dollars a month we already pay for the whole lot. "Be careful what you wish for" and all that.
Honestly, I can't fathom the notion that a DDI subscription is in any way not already *huge* value for money. A missed CB update hardly puts a dent in that record as far as I'm concerned, so I'm quite happy to cut Wizards some slack.
Demanding compensation seemed miserly to me in the first instance, but actually *receiving* it showed a surprising level of generosity from Wizards IMO.
