I honestly don't think the "Vision" questions will ever be answered, as Scott doesn't speak for the entire company, and is probably not authorized to give out that information.
And, quite frankly,
WoTC explaining their private decisions aren't really our business. If there's an executive who chooses to be open about their decisions, they will, otherwise, it's as private as the thousands of business decisions made by public companies every day.
Those are likely to be more controversial than even legal, because the legal questions are mostly publishers wanting some clarification. The "Vision" question involves people wanting to know why Wizards changed the license strategy, and answering those questions is a no-win situation. If it turns out that knowing the reasons why somebody made a decision could cause negative PR, why get into a debate with angry people, or add fuel to their fire.
