In my country during 90s taxes were very high, and no one was paying them… corruption was ripe.
In later 2000’s government realised this and decreased taxes to minimum, now everyone started to pay those taxes! government revenues skyrocketed.
I think extended license prices are too prohibitive, and even when buyer wants to use it in multiple projects, they will opt for normal license, because who will check? I think if we collectively decrease extended license price, there is a chance that buyers will start using it. Buying single license for multiple sites will decrease because you know, price will be reasonable.
