More often I see two or maybe even more software products with the same name. In this case Apache Airflow. The two products serve a totally different purpose. I guess for marketing it would be better to have a unique name.
I'm very curious what even gives you that impression. If you follow the link to their Github, it's got 38.5k stars, 14.6k forks, 3190 contributors, 92 releases, the most recent commit is from an hour ago. The most recent release is from last month.
