Yes, but Google's goals was never to run a semi-public beta. The L developer images were provided so that developers can develop/test their apps on L.
Google never promised updates, never promised stability, it's not a beta, it's not a GM, it's not even alpha. It's simply a preview. You get what they say you get. Don't set iOS's standards on Android, they're completely different products, with completely different cultures, release cycles, everything.
There are a lot of products, Google and otherwise, that go straight to release without any prereleases. If anything Android has has a very strict record of that, so I think your expectations of much more from them on such a large release like L is simply unfounded.
It's more the terrible quality of your posting. You've been given reasonable answers but instead you respond with demands you have no position to be making.
