If you wish Linux to be just exactly like Windows, you will probably be disappointed. GNU/Linux is built by people who simply wish it to be different. In the free software community, members have different visions of what makes an ideal operating system. These differences lead to variety, which is what makes Linux so special and interesting.
Take the emphasis off. Someone quickly skimming might leave with the impression that the emphasized phrase is true.
Some GNU/Linux distributors allow non-free software in order to enable hardware functionality.
This happens because some hardware manufacturers such as ATI do not care about their customers' freedoms, and only release restricting firmware and drivers (some of them don't even release anything, like Broadcom). These are available at no cost (they are freeware) but under restrictive licenses. Distributions such as Ubuntu thus include such components to improve hardware compatibility.
This is outdated. ATI does care. NVidia is a good example of a company that still does not.
