Oh yes it is. But like most products it has its market segment. And that segment is a group that requires a certain function that is not a competitive advantage for any in the group and wants to get that function for the lowest possible cost. Ok, so much for abstractions. A stark example is that on Microsoft's Azure the majority of VM's are running Linux. A lot of companies want cloud based VM's and they don't want to pay for Microsoft's OS to run them when they can use Linux for free, so they don't. Another example is OpenStreetMap. Many companies (including Apple) spend millions a year upgrading openstreetmaps. A lot of companies need a mapping function but it's silly for each one to carry the burden of creating their own map when they can all pitch in and use the final result. This is the market segment where Open Source makes sense.
