Maybe: As the software production chain involves roles with different goals, the InnerSource way of working has to be taken up by everyone involved in the software production chain. For example, business related people as Product Owners may be reluctant to move into a more collaborative and transparent way of producing software. And this reluctance may occur with other roles as well.

Comment
Whenever possible, forces should be stated in a way that indicates the trade-offs (which can hint at the levers by which one can react to a given force). So if Product Owners are reluctant to be more collaborative and transparent, what is motivating them to do so? (Is it a cultural tendency to secrecy to protect proprietary information to gain a strategic advantage? If so, then is it a matter of noting which information needs to be protected vs. which info, when shared, can result in compensating advantages?)

The forces in this pattern likely need to be further brainstormed/developed/analyzed.
