No functionalities are missing to my knowledge. '

The reason to why there are different licenses is because different
people have contributed, as is usually the case with any big open source
project.
Just look at the Linux kernel. That is a monstrous project, involving
all kinds of licenses.

To my knowledge, Ardour is not only partly freely available. It's fully
freely available. It is almost purely, a GPL based project, like most
GNU / Linux open source projects.

If you are interested in investigating the meaning of the licenses, I
suggest you download the full source of Ardour.
Then look up each license for each bit of code to see what they mean.
