Looks okay to me. Not sure how important the last two are to be honest, but I included them for completeness

The marketing statements on the website say the right things too, but they are secondary to the above, obviously:

Openness

OpenCloud is and remains open source software. This means that you can download and use the source code free of charge and without obligation. We welcome and encourage any kind of participation in the work on OpenCloud in the spirit of open source collaboration.

OpenCloud GmbH also offers paid builds of OpenCloud for use in environments where support, professional services and other services are required.

Who are we?

OpenCloud GmbH is a young company founded under the umbrella of the Heinlein Group and employs a team of developers who are familiar with the project code.

The combination of the Heinlein Group’s many years of experience in the open source business and the unwavering enthusiasm of the developers, most of whom have many years of open source experience, provides the perfect foundation for an active project. And we warmly invite everyone to join us!

The foundation

The basis of the project is a fork of a widely used open source project whose components are co-developed by developers from the science organization CERN and other active participants. OpenCloud is now being continuously developed independently by the OpenCloud community and published under the Apache 2.0 and AGPL-3.0 licenses.

In the spirit of reusability of code under free licenses, we are grateful for the strong foundation on which we are building.
