 - There is distrust of contributions due to a past history of cheating: teams submitted half finished contributions and subsequently filed requests for fixes that make it ready for use in production.

 - Each team looks first to help its own leaders achieve their own goals. This direction of loyalty can complicate resolution of this problem.
 - There is a natural aversion to taking responsibility for code not written by oneself.
-- Contributed needs to be heavily rewritten before being accepted into the codebase.
+- Contributed code needs to be heavily rewritten before being accepted into the codebase.
 - There is the fear of the contributors not being available for support with fixing bugs after the time on contribution.
 - Teams fear contributed code will lead to high(er) maintenance costs but do not know how to control for that.
 - Receiving teams may fear that teaching others how to contribute code will expose technical debt in their system and that visibility may be damaging.

The latter can be interesting for organizations that want to show additional information about their InnerSource approach in their portal e.g. for branding and recruitment purposes.
 
 When launching the portal, a communications campaign promoting the addition of InnerSource data files or meta-data to code repositories should be considered, to bolster the number of projects displayed within the portal.
