> All Docker images are glorified tar layers that are compressed with gzip. By definition, all users of Docker are users of gzip and tar. I understand what your point is (it's not as visible) but I don't agree with saying it's "core to more businesses".

Definitely. I was a little unclear, I meant core as in visibility, which you pointed out.

Also about Kubernetes, I can't comment on that because I've heard used it (but I've heard of it). I think it' s possible that there are a lot of businesses out there (such as the one I work for) that use docker but not Kubernetes.

The more visible an open-source project is, the more likely people are to donate to it. I could definitely see companies supporting docker in the same way that they support the Linux foundation or various Linux distros.
