PureOS is the Debian-based Linux distribution by Purism for their laptops. Jonas Smedegaard has apparently joined Purism to help with PureOS:
“I am long time Debian developer with a special interest in Pure Blends (a.k.a. friendly assimilation of derivatives into Debian). Since about a month ago I am hired by Purism to help develop PureOS – a Debian derivative for which I will act as Derivatives Census contact.”

Hector Oron of Debian, who invited PureOS into the Debian Derivative census, made a few interesting initial comments evaluating PureOS, some things that need I hope Purism addresses:
“The page says that PureOS modifies Debian binary packages. It is quite rare that distributions modify Debian binary packages instead of modifying source packages and rebuilding them. Does PureOS actually do this? If so could you describe what kind of modifications you are making? If not I guess the page needs to be fixed. The apt repository for PureOS does not contain source packages [for the contrib and non-free section], including for packages licensed under the GNU GPL. This may or may not be a copyright violation depending on whether or not you distribute those elsewhere. In any case, please add source packages to your repository so that Debian can automatically create patches to be presented to Debian package maintainers.”
