MariaDB asked me to look over their "Business Source License". The BSL is a non-Open-Source license which transitions into an Open Source license after a delay. It's designed to help companies to get paid for developing Open Source by allowing them to make it commercial-license-only for a limited time in which they collect revenue for its licensing, and then the work goes Open.

Introducing the Functional Source License: Freedom without Free-riding
Sentry started life in 2008 as an unlicensed, 71-line Django plugin. The next year we began publishing it under BSD-3, and ten years later we switched to the Business Source License (BSL or BUSL). Last year we purchased Codecov, and a few months ago we published it under BSL/BUSL as well. That led to some vigorous debate because of our use of the term “Open Source” to describe Codecov, from which emerged this helpful suggestion from Adam Jacob, co-founder of Chef:

Mobile Open Source: My Honest Dual Licensing
Excellent post, Fabrizio. Thanks for "just being honest" about dual licensing. I agree with you whole-heartedly.As for Alfresco, our old model was working fine. In some ways, perhaps better. But it never felt right for us. (Some of this was my innate insecurity born of competing with Red Hat's open source message while at mixed-source Novell. I lost there, and didn't like the way we lost. I hated the message I had to say there.) So we went 100% MPL, and the results have been excellent - sales are up, downloads are up, and (most importantly) happiness is up. We really like the change, and everyone in the company and our community is happier.Is it an infallible model? No. But I agree with you - the better we segment our customers, the better our sales/etc. will be.Matt
