I'd love to see some more goodwill copyleft, but it's understandably highly unlikely.
That's why I genuinely respect whoever actually got the whole SRD idea through the Wizard$ of the Co$t boards during the early years of D&D 3.0E, for succeeding in making a miracle...
P.S. BTW I do own the 6E core books + Champions Complete, in both dead tree and PDF formats.
