> In 2008 Facebook itself was in infancy

That's quite an overstatement, to put it very mildly. Facebook was allowing open non-.edu signups by 2006, and the buzz around it from it's school success was immense. By 2008 it certainly wasn't seeing a critical mass of boomers and other late(st) adopters, but it was still huge by any measure - 100 million users, and growing with unprecedented speed.

People were absolutely already uploading phone pictures to FB and other sites by then; I think there may even have been Facebook apps shipping on non-smartphones by that time, it was one of the earliest things carriers used to flog data plans. I agree that "the majority of the world" wasn't uploading phone pictures anywhere by then, but then I'd be surprised if that rather high bar has been reached today either.

The matter at hand is collecting user pictures for mass scale machine learning. I and everyone I know didn’t even join FB until 2011-12. 100m is nothing compared to the current 2.2B user base who is posting annotated 10 year old pictures of themselves. This is to counter the parent comment that “they already have this data anyway”, not an absolute statement on FB growth.
