If you have a commercial product and somebody makes something similar or better then gives it way for free that means it's time to get back to work. About a year ago sombody made a knock off of my Backdrop Tool. I simply made my backdrop better, gave the update to all the existing users and now I have a better product to sell. Am I mad at the other guy? No. I have a better product to sell and it will continue to sell because it's better! Now DAZ has their "Cyclorama" OK, the Backdrop Pro is in the works. It will be even better and a lot easier to use than that other thing. Am I mad at DAZ? No, I'll just make a better Backdrop Tool...
