Steve Hughes explains the implications of sharing a Power BI report:
The primary reason to use share is to distribute content outside the context of a Power BI App. Power BI Apps should be your first mechanism for sharing content within your organization. It requires more thought and planning which is typically a good idea with your companies data. However, there are times when sharing makes sense. With the ability to share reports, you can limit sharing to specific areas. Also, you may want to create a “one-off” report for use in decision making but not something to be deployed in the long term.
Sharing is very different from deploying Apps. App deployment is not that difficult to do, but prevents sharing and is much easier to manage access.
