We are deeply rooted and involved in Debian. The friendships, relationships, and technical expertise we have in Debian have many benefits for Tails, and we are not ready to build the same relationship with Ubuntu, OpenBSD, or any other distribution. See our statement about our [[contribute/relationship_with_upstream]] for details.

Ubuntu is led by [Canonical](https://en.wikipedia.org/wiki/Canonical_\(company\)), a for-profit corporation that takes most of the important decisions.
We usually ship kernels and video drivers from [Debian backports](http://backports.debian.org/). The result is comparable to Ubuntu in terms of support for recent hardware.
