I uploaded a picture to Google Maps once. They told me they needed to access my photos to be able to upload the picture.
A week later I get a notification “hey do you want to upload this photograph of a restaurant you took at location x?”. So Google Maps was busy rifling through my photos while I was going about my day-to-day business.
Yes, they scan your photos and text and look for reasons to report you to a government agency. They can completely misinterpret or fabricate what you have with no real controls other than good faith.
For somethings I think they are legally obligated to do this. It is creepy.
GrapheneOS has storage scopes which make the app think it has full folder/file access but in reality you can choose the exact files or folders to give access. It helps keep invasive apps in line.
