You can get similar behavior with Dropbox https://www.dropbox.com/s/pcutvzhj8nc4auu/indy_asleep.jpeg And OneDrive: https://1drv.ms/u/s!AqxVBILuAH4kssIAdGJhBtwUCm5DhA

{I assume Box has something similar but I don't feel like finding my creds}

The big difference I see is that that the Google Photos share model feels related more to mobile-sharing scenarios than access control - ie, you're sending your buddy a link! Vs you're granting access, and that distinction isn't super blatantly called out.
