IMHO: DataHub - or any tool really - can only help a little with governance. SO much of what is needed is a behaviour question, and that needs much much more than tools: executive commitment, house/system of company governance, clear communications, incentives, support from legal and compliance teams, focus on execution, etc. The tooling almost comes last.

In my experience, I have seen data governance only succeed in organizations with a strong CDO. One who is capable of aligning with the business strategy, collaborating with the other LoB's, and driving change. Nevertheless, I do believe that there is a feedback loop and that your DG-product or catalog might influence how you do DG.

"Its a people problem", not easily solved by the latest, greatest shiny object.
