They dont care. All that matters is what the uploading device is.
I do this with my Pixel 4a, use it to upload all my pictures from my Sony cameras and Fuji camera. Metadata still even says which camera took it.
They stopped this option though, i think the last one to allow this was the Pixel 5. But those devices are all still allowed unlimited standard quality uploads. Great for viewing on phones/tablet. Just not print quality.
So they don’t check the metadata to verify the phone who actually took the picture?
