I personally am just looking for a stable tool to build and test images. I can appreciate that Docker is looking for a way to become sustainable, but the way they are going about doing it has become disruptive to how I use the tool, thus alternatives like podman are becoming much more attractive.

The license fee is really not an issue for me - but continuously having to adjust my workflows when Docker Inc decides to change how things work on the back-end is an issue, and it's much more expensive for me than the license.
