The thing with Flickr is that
1. They've had a freemium business model as long as I can remember.
2. The new free tier may be limited, but it's still more than they offered *before* the move to "Let's get people to host ALL their pictures here!" a few years back. (1000 photos vs. 200, IIRC).
3. They're focusing on their core, not jettisoning it.
