Both open source and free software can be sold.

1. Most projects are not funded at all. In most cases large companies exchange human labor for influence over the project. There are also cases where the company built something for itself and realized the publicity generated by open sourcing it would worth more than the project. And sometimes they are required to because of licensing.

2. The copyright holder can create and change one or multiple licenses anytime it wants. This is why FSF usually requires authors to transfer the rights to them.

Most people think that open sourcing is like throwing candy out of a window. But reality is you can open source you whole website's source code and MAYBE 2 or 3 persons will ever fork it. Robbers will look for money, not work.
