Indeed, this is not open-source: this is public-source. They don't really open the project to external contribution, they just publish their code and continue the project as their tool. They will not have incentive to add features that are not useful to their business even if it useful to the community (if provided by a PR for example), because all the developers of the project are employed by the same company and this company doesn't have any reason to review and fix code that is not part of their business.
