@filippo the difference is clear however. The main reason why I would rather have an open source database is to be able to have my database service managed/maintained by third parties and be able to pay anyone else for the maintaince if I'm not happy with the current vendor. This was possible with AGPL as it's an open source license, it's practically impossible with the SSPL and the intent of the license switch is precisely to make sure the copyright holder has monopoly on offering commercial service and maintenance on the software, much like with other non open source licences.
No reason to especially get outraged however by the SSPL, but the bait and switch method that some vendors used here is frustrating.
