I understand this, and I am someone who started using free software for philosophical reasons. But if you're interested in free software succeeding, it's a better strategy to meet people where their needs are rather than push any particular selling point. If someone switches to Linux because their Steam games run smoother than on Windows, more power to them! And then we can sell them on all the free software that their distribution just happens to come with, and also educate them about the philosophical underpinnings along the way.
