Klomann the only people on udemy who are afraid of rippers like this are the people who make and sell substandard courses. As has been stated before in this thread then if the course is good enough then it will be bought from the teacher to support them. This software provides the oportunity to try before you buy. I could buy every course watch the first few videos then go throu the hassle of trying to get my money back if the course doesn't measure up. Or i could happen on a course by chance, watch the teachings and decide to buy it to support the teacher, without this software many teachers would not have made another sale.
