GitLab are behaving like bad open-source community members. Without freely available open-source software, they wouldn't have been able to create GitLab, turn it into what it is today, and make money from it. And they still need external OSS for that. Giving back to the open-source community should not be dependent on if a person can put food on the table while working on it. The deciding factor should be: non-profit organization or not.
