Trusting a dubious central authority up until you get burned is a bad heuristic.
Just location tracking. The lies. Over, and over, and over, and over again the lies.
I see no reason not to believe that Page and Brin sincerely desired Google not to be evil; but it's the institution decides to do evil, not any individual, so they did not have (or could not maintain, as the organization scaled) the power to guarantee this. No one does.
I scrolled back and checked some pre-2015 photos, they look fine, and then deleted the app.
Maybe they store physical photos and the albums got soaked in water. Sadly it happened to all our 90s photo albums during a flood. Some of the photos were stained really bad.
I uploaded a photo to google maps. A week later it found some random picture of a local park and offered up a notification suggesting that I upload this photo to the destination it had located in the maps app.
How on earth are they doing this without "scanning" the photo? Seriously, please tell me.
