Shouldnot Facebook come out openly and apologize to the users?

When you have a serious flaw like exposing private chats shouldn't you say i am sorry? Even Google did it.<p>Facebook Reaction: “For a limited period of time, a bug permitted some users’ chat messages and pending friend requests to be made visible to their friends by manipulating the “preview my profile” feature of Facebook privacy settings. When we received reports of the problem, our engineers promptly diagnosed it and temporarily disabled the chat function. We also pushed out a fix to take care of the visible friend requests which is now complete. Chat will be turned back on across the site shortly. We worked quickly to resolve this matter, ensuring that once the bug was reported to us, a solution was quickly found and implemented.”<p>Where is the apology here?
