1) Linux is made of many distros, each one with their own strong points and features. Many different maintainers matain them. There is no single point of funding for them.
2) Mozilla on the other hand makes basically one semi well-known product.
the way i see it mozilla has one thing to do, and didnt do it very well.
the linux GNU gang has a mountain to contend with and has has moved a mountain.
so what would be the secret sauce that mozilla doesnt have.
