GitLab is mentioned on the advocacy page https://giveupgithub.org/. GitLab is an open-core business, which means there is a permissively licensed FOSS version and a proprietary version. The gitlab.com website uses the proprietary version. In addition many features of GitLab don't work at all or work much less well if you turn off JavaScript. They have swayed a lot of ostensibly FOSS, copyleft-leaning and privacy/security-centric projects to use it, despite the business model and license.
