The fact that you're reading an article about a paper Google just published suggests it's not as closed as your doomsaying might suggest. Also the paper notes that Google is one of the largest contributors of bugs and CVEs to KVM, which is a security tide that will raise a lot of boats.

I don't think your use of "doomsaying" is fair, and detracts from a useful comment.
