So I am perusing the additions in the new 1.7 version and came across the "Stock" tab. Three services are there for free stock photos. For the sake of this discussion I'll focus on one of them... Unsplash. The following is a quote from their license page: "More precisely, Unsplash grants you an irrevocable, nonexclusive, worldwide copyright license to download, copy, modify, distribute, perform, and use photos from Unsplash for free, including for commercial purposes, without permission from or attributing the photographer or Unsplash." I don't even need to join... the images are just "there"! High quality, high resolution, searchable... over 800,000 of them! This is just crazy. And their website is well designed to boot. How do they generate revenue?
