Given the examples of promoted API usage, it doesn't seem to have any backing away from their stance that they don't want third party clients. Add to that their API pricing was as I understand it not feasible for any new client app used by end users which gets any serious amount of usage and needs to move to paid tiers.
Don't get me wrong, I wouldn't mind them touching on the developers relations they want to build, but no company of their size will admit to wrongdoing in the past.
Also words aren't worth anything unless they come in a legally binding contract that can't change on a whim.
