I dont know, what you read. But I read, that Oracle shut the door until three months before the scheduled release. Oracle is the specialist on software development and not their client. So if Oracle says not otherwise, they have to deliver. If those allegations are true, Oracle is to blame for the majority.

Or do you want to lead your local bakery in how your breads are made? The baker has to know, when and how to include the client, because he/she is the specialist.
