Well, rumours or not, i know for a FACT of one FS9 dev that created such a great addon, gathered more than 1 million users , and made MS create the same addon for FSX as a sim feature thus sending this developer out of the loop (not that he needed anymore..i guess..:d:d)
Anyway, as times changes and basement hobbies start to grow into full industries it was bound to happen (I still remember the early days of RC flying, you could get blueprints rigth from the magazines, or just for a few bucks on the mail...)
The other side of the coin is that most of these (if not all) addons and the sim itself are being used for real training in more than one way (MS created ESP for this purposes).Interesting days are coming into this brand new industry...
