But that is sort of why it's the first step. You were using Windows and were bothered with ads. So you may have looked into an alternative you heard about called Linux. You are new to Linux and maybe ask some questions on forums and interact with people from all over the world that are taking time out of their day to help you, which gives you a sense of community. Then you learn that Linux is licensed as Open Source Software, and that people are working together to create something for the benefit of people, not for profits. Then you start to wonder, what else in my life that bothers me is a result of profit motivation?

You mean the picture is a windows ad ? [edit] typo
