Certainly these people are communicative, but that doesnt make them transparent. In my mind transparency implies an outsider having a reasonably accurate picture of the true state of affairs. These people (some of them psychopaths) will go to extraordinary lengths to convince as many people as possible that they are doing the great thing.

>They will be able to talk at length about what they are doing and how it will make everybody's life better

There is no crime in this. Everyone should think about these things. But I would argue that the malicious people need to spend more time communicating with many people to manage their perception - its almost like a propaganda war.

>openly promote transparency

This is vital information. If they openly promote transparency, you can use this attitude to suggest and implement real transparency in systems and workflows. Most of these people will recoil in horror at the idea of being exposed.
