It includes most of the text and provisions of the GNU Affero General Public License version 3 (AGPL v3), but modifies its provisions for software that is conveyed over a network—requiring that anyone who offers the functionality of SSPL-licensed software to third-parties as a service must release the entirety of their source code, including all software, APIs, and other software that would be required for a user to run an instance of the service themselves, under the SSPL. In contrast, the AGPL v3's equivalent provision covers only the licensed work itself.
The SSPL is not recognized as free software by multiple parties, including the Open Source Initiative (OSI) and multiple major Linux vendors, as the aforementioned provision is discriminatory towards specific fields of use.
