I am going to put a different spin on this: If you use a service like google photos, wouldn't you want to uplift all your photos, albums and metadata into the service?

Viewed from the "be maximally useful" perspective, it makes sense. I have 150,000 photos (maybe) -I don't want to approve each one. Even at the album granularity, I have thousands of albums. We all do.

Yes, its a giant, egregious privacy breach. That is pretty much definitional for a cloud based Photo archive/album service.
