The copyright for GrapheneOS code is entirely owned by the GrapheneOS developers
+ and is made available under OSI-approved Open Source licenses. The upstream licensing
+ is inherited for the modifications to those projects and MIT licensing is used for our
+ own standalone projects. GrapheneOS has never had any copyright assignment and the
+ developers have always owned their own contributions.

The tiny portion of the code written by people under contract with the former
+ sponsor has not been included in the project since it was ported from Android Oreo to
+ Pie in 2018. This code became obsolete and was no longer useful. The vast majority of
+ the code from the previous era was owned by Daniel Micay, with very few exceptions. It
+ was never written under any contracts or employment agreements, was never assigned to
+ any company or organization and was the continuation of the original independent open
+ source project. The code was originally published under the same permissive open
+ source licenses that are used by GrapheneOS today. Only a small portion of this
+ historical code is actually still in use today. Most has become obsolete or has been
+ replaced by rewrites taking better approaches than in the past.
+
+
There was an era from September 2016 until the project split from the former
+ sponsor in 2018 where non-commercial usage licensing was used for revisions to the
+ existing permissively licensed code. This was an attempt to prop up the sponsor that
+ was supposed to be supporting the open source project. This did not impact ownership
+ of the code and Daniel Micay has relicensed the portions of the code that are used by
+ GrapheneOS. GrapheneOS does not contain any code based on code under non-commercial
+ usage licensing. Great care was taken to avoid pulling in anything that was not solely
+ owned by Daniel Micay, which was the case for nearly everything in the project.
