This is why the Internet of Things terrifies me. You think these clowns wanna be responsible for promptly releasing security updates for the lifetime of every piece of hardware they've ever shipped?
Although telecommunications always had a very close relationship with the software industry, they see the customers in a different way.
Since the early days they would rather ship new phones than offer upgrades. Nokia was probably the only exception, in the models that weren't tainted with mobile operator firmware.
It only works for Apple, because they managed to get those guys out of the way. But they got their lesson and surely will not let others get away with it.
