The open source model allows the freedom for anyone to view, modify, and distribute source code. The Linux kernel and the many distributions that uses it are released under any given open-source license which allows anyone to build their own Linux distribution at will.

Unlike Microsoft Windows, you don't need a license to download, use, copy or give away Linux or the many distributions associated with it. Linux is actually the kernel (the heart) from which many distributions of open source operating systems radiate outwards. Ubuntu, Linux Mint, are just two of many popular operating systems that are entirely free.
Linux :-)
No one, its open source.
