To expand for those not reading German, the response is basically pointing to and restating https://about.gitlab.com/privacy/#data-retention

> GitLab reserves the right to delete inactive accounts, projects, namespaces, and associated content. GitLab may deem an account, project, or namespace inactive based on various criteria, including, but not limited to, the account creation date, the last time there was a valid log-in, and the date of the last contribution. If we plan to delete your account or projects, we will provide advance notice by sending a message to the email address registered to your account. GitLab encourages you to utilize your account on occasion to avoid the risk of being deemed inactive.
