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

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/
