The article portrays Docker containers as an alternative to binary packages that is typically mistaken for virtualization. If we take this train of thought, we end up with a system that is bloated, overengineered, brittle, and heavyweight. It's not to Docker's credit.

No, the problem of VM is not virtualization, but the notion of "machine". What Docker really does is to get rid of the full-blown machine/guest os, and focus on app. As such, you can run Docker image with Linux container for sure, you can also run it with hypervisor, which is surprisingly fast to boot too (<100ms).
