This sort of thing seems to be getting more and more common with Apple. They seem to announce their stuff long before any partners have signed up. Newspapers and magazines are another example. We heard all about how every magazine would be available and how Apple was going to change the whole industry, but the reality is VERY different.
Now Apple announces Facebook functionality before any deal is cut, while at the same time trying to use a public statment by the CEO to vilify Facebook and make them into some sort of greedy bad guys. That sort of negotiation tactic is nasty and amateurish.
This sort of sleazy tactic is far beneath Apple.
Apple never announced Facebook for Ping.
Kara Swisher asked Steve point blank "Why no Facebook integration." He gave the answer that the terms Facebook demanded were onerous to Apple. This is a fair negotiation tactic. It certainly is no less fair than Facebook blocking the API access to Ping in the eleventh hour so that Apple was forced to either cave in to the demands or change their plans last minute. Apple chose the latter, which is why you have all of the evidence out there about Facebook in Ping (and why you look at this as if Apple ANNOUNCED anything). The screenshots and documentation are simply overcome by events because Facebook shut down the API access and Apple didn't cave.
All is fair in love, war, and negotiation, and it seems to me that Apple and Facebook are simply playing hardball with each other. In terms of social networking, Apple is in a new position: it is not the Gorilla in the room. Facebook is. So don't look at this like an example of Apple running roughshod over the little guy.
