Why this chart on IoT is incorrect?

I found this picture, which shows huge number of interconnected IoT devices over the internet. So, what is wrong about this picture? Everything!
The correct situation is that each IoT end point device is communicating with a specific cloud-based service which delivers outstanding operating and cost benefits. This is the reason why organization get excited about IoT ecosystems.
The IIoT is completely different story, and there is a huge difference between IoT and IIoT. The IIoT devices (smart sensing devices) never communicate directly over internet (as IoT devices do) as they are part of the ICS architecture which must be cyber secured. When IIoT ecosystem service is required (upon detecting a problematic condition or need for optimized performance), the ICS initiates a communication session through corporate IT with the cloud based service and vice versa.
