I'd like to you to refrain from spreading unwarranted conspiracy theories.
There is no need to sow discord with such assumptions. If there was a breach that compromised account security EA would have notified its users.
If I had any information on why EA decided to push ahead with the SSO on short notice, I'd have given the community more information. But in the end, this would be little more then blame shifting anyway, and there is no place here for that.
We are still working on this however. While we wait for EA's go on the server move we are working on the services today to increase stability further. Fortunately we can update those part of the games without any mayor downtime for the players.
