Business Source License

[remram44]

The Business Source License (BUSL-1.1) should probably be mentioned. I personally like it because it has a trigger changing the license of a particular release to an opensource license after some time (e.g. 4 years). So while it is still not opensource, it is "eventually opensource" (though never the latest version).

This makes it similar to other licenses (e.g. Commons Clause) but removes the risk of software becoming unusable because the company stopped maintaining it, since it eventually becomes opensource.
