I believe this is exactly the policy that was followed for designing 4E. And that led to these debates we are having now. If it had worked the massive base of new fans would drown out any grognards pointlessly trying to suggest how they could do better next time.
(And no, I don't think 4E is an mmo or a card game. I do think that the heavy focus on easy to DM, etc... was clearly aimed at those markets, and there was a ton of talk about exactly that during the lead up to and early months after release. Of course, at that time the spin was that us "grognards" wouldn't be missed because we would be replaced by so much new blood. Now that exact same point is just being moved from it not having happened for 4E to how it so clearly will work for some future game.)
But it didn't work, becouse they tried to beat videogames in their strongest point: gamism. Plus many of the 4e targets failed in its implementation (for example, it was a 4e target to reduce combat length. It didn't work, combat are even lengthier. But the diagnose was correct anyways: you need to make the combat faster. Just that some of the decisions they made for that (like changing permanent bonuses for situational bonuses) were wrong.
