Change license to BSL

[onderceylan]

To create a sustainable business over OSS, we're considering changing our source code license from MIT to the Business Source License version 1.1 (BUSL 1.1). This license allows software providers like us to control how their source code is commercialized while still publishing the source code to the community. The BUSL 1.1 was originally introduced by the founders of MySQL and MariaDB, and first applied to MariaDB products in 2013. It was updated and clarified in 2017 as version 1.1, after consultation and advice from Bruce Perens, co-founder of the Open Source Initiative (OSI).

BUSL 1.1 is a source-available license that sets three tenets to the license, some of which are customizable and specified by each licensor.

• BUSL v.1.1 will always allow copying, modification, redistribution, non-commercial use, and commercial use in a non-production context.

• By default, BUSL does not allow for production use unless the licensor provides a limited right as an “Additional Use Grant” – this piece is customizable and explained below.

• BUSL provides a Change Date usually between one to four years in which the BUSL license converts to a Change License that is open source, which can be GNU General Public License (GPL), GNU Affero General Public License (AGPL), Apache, etc.

At Elegant, we're considering our Additional Use Grant to allow BUSL-licensed Elegant work in production when your application is built for demo purposes, educational purposes, non-commercial reasons, or for a non-profit organization. We have set the Change Date to three (3) years, and the Change License to GNU Affero General Public License (AGPL), Version 3.0.
