Docker for Windows/Mac uses a single VM for all your containers. Firecracker/Ignite has a dedicated micro-VM for each container - a completely different architecture, with much better isolation between containers. And the 125ms boot time is not something you get with a typical VM. But I do agree that they don't explain how Ignite is different from "wrapping a container in a VM layer" that Kata/gVisor does.
