I have a similar thing with the google photos app. Almost every day it asks "You photos are not backed up, enable it now". I say no (obviously). Then it asks "But maybe you should backup these 100 images?" Pretty please?! Clearly 100 images is enough to build a good profile.

It's a usability issue, not a privacy issue.

Google photos are closed source. For all we know it could have analyzed all your photos locally and trickled the result to Google servers a thousand times by now.
