Wonderful e-mail!
I will print it and put it in my office door.
Geo4All does not have a Pro version!

> 1. Cesium is truly open-source as defined by the Open Source Initiative
> [2].  Cesium uses the Apache 2.0 license (an OSI approved license [3]),
> follows the Contributor Covenant's Code of Conduct [4], has dozens of
> contributors not employed by AGI [5], has public roadmap discussions where
> everyone is encouraged to participate [6], strictly follows Contributor
> License Agreements [7], has tons of documentation to create an inclusive
> community for new users and contributors [8, 9], and is considered by many
> to be an open-source community success story [10].

> 2. In addition to creating a genuinely useful software project that has,
> for example, proved to be a successful successor to Google Earth [11] and
> widely used at NASA (search for "NASA" in [12]), the Cesium team is now
> creating an ecosystem including open formats to move the 3D geospatial
> field forward without vendor lock-in.  These formats include glTF for
> efficient 3D models [13], an open standard that we created as part of The
> Khronos Group (who also maintain WebGL, OpenGL, COLLADA, etc), and 3D Tiles
> for streaming massive heterogeneous 3D geospatial datasets [14].  We've
> fostered these formats in openness by having spec development, editing, and
> discussion in GitHub repos.

> 3. The existence of a Cesium Pro version does not imply that open-source
> Cesium is a distant second.  Cesium Pro could more literally be named
> "Cesium with niche aerospace features."  It serves a narrow market that
> creates funding for the sustainability and rapid development of the broad
> open-source Cesium.  AGI is passionately supporting open-source Cesium for
> the long-haul as all our new initiatives are built on it.  We would, for
> example, never make the core terrain and imagery engine faster in Cesium
> Pro, but not open-source Cesium.  The tangled fork alone would be too much
> work to maintain.  Open-source Cesium will remain first rate and use only
> open formats so, for example, data sources can come from any vendor, with
> open- or closed-source software.

>
> Also, one thought for criteria for Geo4All's endorsement: consider a
> minimal first requirement of only using projects with OSI approved licenses
> as this comes with many guarantees about the open use of the project [3].

> Finally, I suggest avoiding terms like "license free" since if a project
> does not have a license, it is technically "all rights reserved."  I would
> also try to avoid "commercial" in some contexts since, at least in the US
> government's eyes, open-source software is commercial software [15].
