That Smartstore rejected to meet nopCommerce license terms is MORALLY WRONG. Maybe their lawyer will try to find legal loopholes or weaknesses in Nop licence to prove that this is not illigal but remember that slavery was legal and intellectual property rights are not always protected. Furthermore in smartstore.net site there is no recognition whatsoever that its was derived from Nop. Maybe Smartstore guys want to look as the original developers.
Users of Smartstore products are morally supporting property rights piracy.
We used to be also very enthusiast about Smartstore and were working on some tests, but after long consideration reading all opinions in the Nop vs Smartstore case, we have decided to quit and go for Nopcommerce, even if Smartstore actions are declared "legal" in court. We have talked with our clients and they not only approve but praise our move.

Thanks Nopcommerce for this great software and congratulations for taking this case to court
