I think one part of the problem is that we don't have a comprehensive catalog of our dependencies and their dependencies (and so on). Having such list helps us understand hidden patterns in our infra ("we are depending too much on facebook products") or try to reduce complexities by harmonizing them (http://boringtechnology.club/)

At least having a structured catalog is a good starting point IMHO.

I suspect there's much more than just this list, even if we just restrict it to "major" components.  On Analytics, we've had to adjust as the following systems EOL-ed or changed licensing:

* Pivot (moved to Turnilo, a fork)
* Camus (moving to Gobblin)
* Kafka Connect

Hello,

Yes that is ElasticSearch. They have recently announced they are now licensing code under Server Side Public License (SSPL) it is a viral license which in short requires that any service based on such code get licensed with the same license.  I am not a lawyer, but I guess that would imply that our whole stack switch to it as well.  As such it is not considered free by Debian or the Open Source Initiative (OSI).

As I understand it, the move has been made possible since all contributions were subject to a Contributor License Agreement (CLA). So that although the code was placed under a free license, the CLA effectively grants unrestricted publishing right to an organization, they can thus relicense the code however they want.   If I get it right, the old code is still under a free license but it can also be used under the new non free license.    As I get it the move has been done due to frictions with Amazon which is providing a search service.   Amazon announced they would be behind the free community fork: https://www.opensearch.org/
