I don't really understand what all the outrage is about. This is like me walking into the local shop and picking up a newspaper that until recently was free. The shopkeeper then informs me that it now costs money, and I put it back on the shelf and walk out. The shopkeeper typically doesn't throw a hissy fit if I do this. Likewise, my son typically doesn't throw a hissy fit when I tell him that he needs to make his papier mache artwork out of the junk mail that get shoved through our post box, instead of the formerly-free newspaper I used to get for the job.

It's not often that I side with Facebook on anything, but this just sounds like a case of Facebook being told that they need to pay if they want to use a resource, and Facebook saying "OK, we won't use that resource".
