Understanding copyleft

Copyleft is a legal way to use copyright law to maximize rights and express freedom. However, it impacts our products. We must meet all obligations of open source and free software licenses.

When building a Linux distribution, at least two projects are used: the Linux kernel and a compiler. The GNU Compiler Collection (GCC) is still the most commonly used compiler.
