I consider google with android to be a similar position to the linux kernel on my servers. I don't expect any of the kernel team to produce a patch for my 2.6.18 kernel I am running on a RHEL 5 system, I expect Red Hat to do that. Why doesn't Samsung / LG / HTC manage Long Term support for Android versions, back port the patches and roll them out? Alternatively why don't they all pool together and manage an LTS version for customers. It seems crazy that the company that has a relationship with the customer doesn't have to support the customer, and everyone instead blames google who wrote the code. The android vendors could back port, create alternative patches or simply make the device able to be updated to a more recent version.
