How have you dealt with possible overlaps between Product Managers, Business Owners and Marketing?

I was just reading an article by Marty Cagan about the scenario of Business Owners "versus" Product Managers, especially for companies using a matrix organization. Now, I'm living in a similar situation, and not only in the case of Business Owners, but it seems that depending on the side of the organization, the scope of Product Managers is divided more than expected, causing various types of issues. So, I'm curious if other companies, big or small, have also had to deal with this. Here's the link to the article: https://www.svpg.com/product-managers-vs-business-owners/
