What do you mean by “compiling photos to replicate a similar or competing service”?

In the Unsplash License, we state, “This license does not include the right to compile photos from Unsplash to replicate a similar or competing service.” What we mean is if for example you were mass scraping or crawling images from Unsplash and using those photos to build a site just like Unsplash where your users could download, copy, modify, distribute or use photos originally found on Unsplash, for personal or commercial use.
