I have fixed the year in the license.
As for the license itself, the platform code is not opensource or free software if that is what you are wondering. We contribute to opensource in other ways both financially and with development - https://www.cloudron.io/opensource.html . The license text is an adaptation of various other licenses like GitLab EE, Sourcegraph EE license etc.
All our app packages are opensource. All the code is at https://git.cloudron.io/
