> 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.

This probably qualifies it as a service, but since it looks like gitlab doesn't install it or redistribute it Elastic isn't going to come after them (if they don't use SSPL code then SSPL doesn't apply). Plus, GitLab is effectively open-source, so they might meet the qualification for using SSPL anyways. Of course, I am not your/a lawyer.
