"So unless your phone says “Nexus” on it, you’re not running true Android. And Samsung’s Galaxy Nexus, for example, accounts for just 0.5 percent of the smartphone market. It’s a safe bet that there are more people using jailbroken iPhones than Nexus phones. If I were a Google engineer who’d poured his time and effort into the beautiful Android 4.1, aka Jelly Bean, I’d be pissed."
It's even worse when you consider that many people pick up the Nexus devices for the unlocked bootloader so they can root their phone and run custom roms.
