Seems worse than GPL and AGPL, where you can use software, as long as do it across process boundaries and don't link to it. I.e. you can run GPL mysql without any worries. And only the bits that were linked to the GPL code needed publishing.
The REDIS spin was much more forgiving and likely more pragmatic as well. Only some particular value-added modules were shoved under their new license. I use REDIS and see no problem with that at all, it's a reasonable compromise between openness and paying the bills.
REDIS aside, never been a big fan of Mongo and NOSQL and this won't be changing my mind. Basically I fail to see what use case you would have, as a for-profit entity, for running the risk of using it with the new license. Perhaps if only your data is something you need to keep to yourself?
13. Offering the Program as a Service.
If you make the functionality of the Program or a modified version available to third parties as a service, you must make the Service Source Code available via network download to everyone at no charge, under the terms of this License. Making the functionality of the Program or modified version available to third parties as a service includes, without limitation, enabling third parties to interact with the functionality of the Program or modified version remotely through a computer network, offering a service the value of which entirely or primarily derives from the value of the Program or modified version, or offering a service that accomplishes for users the primary purpose of the Software or modified version.
“Service Source Code” means the Corresponding Source for the Program or the modified version, and the Corresponding Source for all programs that you use to make the Program or modified version available as a service, including, without limitation, management software, user interfaces, application program interfaces, automation software, monitoring software, backup software, storage software and hosting software, all such that a user could run an instance of the service using the Service Source Code you make available.
