If one had no intent to have any form of real open license to begin with, one would benefit the most by delaying that revelation as opposed to making it clear up front. Delaying the announcement places those you view as competitors in a state of waiting where actions cannot be determined and then marketed. This would allow you the most time to work on your own marketing and customer migration unhindered by the efforts of other companies. It also allows a greater time to unwind to the customer base how detrimental the loss of an open system is to them. It's like pulling the band-aid off slowly enough that it's not noticed. Customer choice is not benefited by a closed system when the previous system is open.
Also, by appearing to ask for "input" one gains information from one's competitor about potential products and lines of attack that one may have not thought of alone. By asking for "input" one continues the delaying time-line (composed of initial statements, Q&A sessions, private conversation, bureaucratic hold ups, unexpected legal changes, etc) before the revelation process, providing the best chance that competitors will delay making business decisions for the longest time possible. Done properly, one could not only increase your product's success, one can damage the business of the competitor. If done properly neither the consumer base or the competitor will be aware of what has occurred.
