I'm fascinated at your characterization of both Kafka and Spark as being absorbed by Amazon.

AWS offers hosted versions of each. They are not, as you say "rebranded and for sale", but rather are hosted services, running whatever upstream releases.

But to say that the project as been absorbed by AWS (in either case) is simply false. Spark is developed by a community of numerous companies, of which Databricks is usually most prominent. Kafka is likewise a community of several organizations, of which Confluent tends to be the most influential.

Yes, Apache is (and always has been) business-friendly. The license enables companies to profit on those projects. But, for the most part, companies that benefit from those project also contribute back to them, as a way to ensure sustainability. That's how it is supposed to work.
