This seems... ambiguous, actually. I for one automatically took "free users" to mean free users of the CI/CD feature, not free users of GitLab. Meaning, the set of people who use > 0 CI/CD minutes. I'm actually surprised if that's not what they mean, given the entire point of the discussion is about how this affects users of the CI/CD feature. It's one thing to state things clearly and let the reader make incorrect inferences just due to natural assumptions, but writing the text itself ambiguously to induce that effect is a little different.
