Some applications supply even a full version of FSUIPC… and of course that is calculated in their price to you. As enduser you buy then indirect for this key license… now has the average simmer more the one airplanes installed into his flightsimulator… and each time you pay again and again indirect for FSUIPC. To keep his profits on a certain level, what you want to do as businessman, he has to raise his price. This developer has to obtain a developers key license and that cost his profits. For example, you buy an airplane from a third part developer which requires FSUIPC to work. You think then probarly you dont pay any penny to that greedy developer…. Okay you can get FSUIPC for free, the base pack version. Since then we have to pay for a stupid little DLL what has been developed with the help of the FS community… Then suddenly one day he realise that he can make some money with FSUIPC to built his own cockpit at home. If he didn’t do it, sure that someone else would do the job. Without the support of the FS community he was not able to write it as it know it is these days. Everyone was happy and the entire FS community was a kind of beta tester of his small application. A small DLL what expose only some variables from the flightsimulator to connect with other applications. Has FSUIPC turned into a financial milk cow for Peter Dowson? Oh yeh it does! It all started as a freeware add-on for the flightsimulator.
