Wow. What a disappointment.
I started saving my photos with Google for two reasons: - I’m an iPhone user and didn’t want a single company to have access to all my assets, - it was free and this compensated for the discomfort of using a non-native app.
Without the second argument it makes total sense to look at other, more privacy-oriented providers. Since Apple tries to rebrand itself this way, I would expect more former customers to go there.
