Facebook has decided on quite the way to convince people to download Moments: by threatening to delete thousands of photos if they don't.
The notice has to do with a photo syncing feature that was recently removed from Facebook's main mobile app. Starting in 2012, the core Facebook app was able to automatically upload photos from a phone's local camera roll to a private album on Facebook. They were kept there for storage, but also to make it easier to later share them publicly on Facebook.
That syncing tool has now been moved out of the core Facebook app and into the photo app Moments. Facebook made it clear that this would happen — and in fact it happened months back, seemingly without much pushback. What Facebook was less clear about was what would happen to photos that had previously been synced.
More from The Verge:
At the time, Facebook mentioned that people would be given the chance to download their pictures in a zip file if they didn't want to move over to Moments. Now it's clear that offering is because Facebook intends to completely delete synced photos if people don't download this new app. (This only applies to auto-synced photos; not photos a person has personally uploaded.)
