I must say that I do not understand your source of disappointment nor do I think the word illusion in any way applies to the state of things.
The Kaltura Core platform is indeed open sourced and includes but is not limited to, the following components:
Many additional repos are entirely FOSS and a full list of these can be seen here:
Mostly, the projects/products are licensed under AGPLv3 and a license file is included in each repo and is also declared in each package [RPM, deb and NPM] metadata.
On top of this FOSS infrastructure, Kaltura also offers commercial, closed source, proprietary products, such as Kaltura MediaSpace, LectureCapture and others and a SaaS ENV, based on exactly the same code as in the aforementioned source repositories. This was never denied by Kaltura nor was an attempt to mask that fact ever made.
In fact, this is clearly stated in the README in, among other places, our CE packaging repo:
Kaltura Inc. also provides commercial solutions and services including pro-active platform monitoring, applications, SLA, 24/7 support and professional services. If you’re looking for a commercially supported video platform with integrations to commercial encoders, streaming servers, eCDN, DRM and more - Start a Free Trial of the Kaltura.com Hosted Platform or learn more about Kaltura’ Commercial OnPrem Edition™. For existing RPM based users, Kaltura offers commercial upgrade options.
I’m afraid I don’t understand what you mean by this but will be happy to get a clarification and discuss further.
Reiterating my opening statement: Kaltura CE, which consists entirely of FOSS components provides a complete infrastructure upon which, one can run a fully functional video platform, including: source media analysis and transcoding, setting and retrieving metadata for your media library, customisable player, remote storage/CDN integrations for media delivery and much more. A RESTful API is extended, allowing anyone to create additional applications and integrations on top of this infrastructure, which is, incidentally, exactly how our proprietary components achieve their goals.
As also mentioned above, Kaltura CE includes two management consoles, both licensed under AGPLv3: the KMC and Admin Console. These let you, among many other operations, manage users and their permissions.
I will gladly address any additional points or clarifications you choose to make,
