> With Server Side Public License (SSPL) it's an even bigger shit show, as it forces any business that uses the software to release under the very same license all software and systems and even user interfaces (?!) that directly or indirectly interact with their project. As it is very easy to understand, this prohibits any company from adopting any software released under that license.

Not "any business", only a business that offers a hosted version of the software. AWS has a problem offering a hosted Redis service, but no one who self-hosts (including running it on a cloud) is affected.

Does "hosted version of the software" mean that the hosted service has to exactly match the API semantics to count? Or does it mean any service that's semantically similar (and powered by) the software (e.g. simply storing and retrieving data on a user's behalf)?

Or does it mean something else?

Where is this actually defined?

The license defines it: "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 Program or modified version."

I'm definitely not a lawyer; but as a layman I would interpret that as meaning you can't just change a few cosmetic things in the API to get around these terms, since that clearly still "entirely or primarily derives from the value of the Program or modified version" as well as "accomplishes for users the primary purpose of the Program or modified version".

There's certainly edge cases here which I assume will remain a gray area unless they're eventually worked out in court as part of some lawsuit. But given the intent of the license terms and motivation for adopting it (preventing cloud providers from reselling infrastructure software as a managed service), I would really not expect to see lawsuits against non-cloud providers. I mean there's no logical motivation whatsoever for vendors of SSPL-licensed software to start suing random users who aren't competitors. If they wanted payments from all self-host users, they would have used a very different license.

So my guess is the only way this goes to court is if a cloud provider blatantly violates those SSPL terms, which seems unlikely to happen.

Alternatively, I could just use Valkey and not worry about being sued.

I have more thoughts on this, but seeing as you already ignored the several sentences I wrote after the one you've quoted here, I suppose it isn't productive to discuss further.
