For the GNU or Free software foundation, I tried to sign up. They claim to be free, give people freedom. But, if you try to join their community, you have to pay. At the same time, companies are using open-source technologies to sell their products for money. I think this is just their ways to make business, just a different model and I don't really think it is about the people, because at the end, someone has to make money. Please, correct me if I am wrong. I just want to understand more about Free OR Open-Source!
