SOLVED: RSS VIEWER Missing from SharePoint Foundation 2013

If you read the dozens of threads around this problem you will be told that the real problem is that for you to see

EDIT (page) > INSERT > WEB PARTS > CONTENT ROLLUP > RSS VIEWER

you need to turn on:

SITE SETTINGS > TOP LEVEL SITE SETTINGS > SITE COLLECTION FEATURES > SHAREPOINT SERVER STANDARD SITE COLLECTION FEATURES

but you can’t find that feature, and after working with Microsoft Partner Support for 4 days I can tell you that is because it does not exist in FOUNDATION!
