Not defending Intel, just trying to understand their position other than just being negligent. Wouldn't it undermine most users if the security flaw had leaked before major OS fixed it? The more you share, the easier it is for a leak to happen. So they could have decided to share only with the major OS first and then later, once fixes have been implemented, expand this to other interested parties?
