Power BI Report web part for SharePoint Online Discussion

I just don't understand where and why the thought of needing to have a pro license came into the picture for Microsoft.  Like has been said before, if someone actually has access to the report, what are we paying for?  The ability to consume the report through a different medium?  Is the issue here consumption and using the web part to surface reports potentially public (for the whole company public, not for public meaning for the world), thus increasing resources to host/process/display the data?

That's the only rationale I can come up with as to why they would require a pro license for VIEWING purposes.  Microsoft, help us understand here, that's all we are asking for.  Clearly this doesn't make sense to your clientbase as most people are scratching their heads at this point.
