My experience?
AS EXPECTED AND PREDICTED. This was such a "No duh" situation as that it could have saved literally millions of dollars by killing it before it ever went live. CHOICE is not as great a thing as people like to think. Is it important to avoid lock in? I'd say yes. Is it so important that launching a multi-million (billion?) dollar charge against it half cocked is the right way to combat it? NO. Especially when people LOVE the experience the lock in gives them.
