Earlier quoted context omitted.
It seems that “younger generation” programmers underestimate the value of governance in OSS. The recent Terraform kerluffle couldn’t have happened if Terraform was in the ASF, etc.
There is a quote: "When you stop growing you start dying" (William S. Burroughs). I am not sure I believe that the kind of governance that Apache is providing is helping to grow the projects under its supervision. Your comparison to Terraform is also interesting. Apache Kafka, for example, has been absorbed by Amazon (MSK). Apache Spark is Amazon EMR. Just looking through Amazon's paid service offering I find several…
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.
