The docs still say the Elastic license is used but looking at https://github.com/ubicloud/ubicloud/blob/main/LICENSE it looks like the project might have switched to GNU Affero General Public License v3.0 in the last day.
The linked page at https://www.ubicloud.com/docs/github-actions-integration/qui... still says "Source open under the Elastic V2 license", and https://www.ubicloud.com/docs/about/pricing still says "it's open and free under the Elastic V2 license". Not sure if those were missed or if the docs just need some time to refresh from their sources.
