Actually no. Google is merely the developer of AOSP (Android Open Source Project). The actual implementation and pushing of updates is up to your OEM or phone maker. Some OEMs are graceful in pushing updates, others aren't. But none to my knowledge pushes forced updates that user can't disable? Besides, you can always Flash/Root/etc. in the Android world with the power user shoes when something goes wrong, you can't do that in the Apple world.
