Have you considered using a license like Business Source License (BSL) that would eventually become a true OSI license, like Apache, after a few years?

I think it's valuable for old source available code to not bitrot away when the value of it to the company decreases.

Absolutely, we picked the path-of-least-resistance license for the initial release in order to get the code into the open, but we'll continuously evaluate and see whether switching to a license like BSL makes sense. It's been awesome to see the evolution of licenses in just the past few years, and there are a lot more options than when I started this project. Hoping that having the project public will enable us to build a community and gain continuous feedback that will help drive technical, licensing, and other decisions in the future.

Considering how much Confluent depends on Kafka, maybe you should consider tying a future version to whatever license is used at Kafka, so you can give your users the freedoms that Kafka gave you.
