All of the consumer devices tied to backend services
are a perfect example
of devices that are absolutely useless once a company fails.
Unfortunately,
revenue models based on this model are on the increase.
No, it isn't.
I'm yet to see a consumer device tied to a backend that cannot be
reverse-engineered. Take a look at the MS tv boxes, as an example. Nowadays
it is EASIER to figure out how something works than before, because we have
the internet, we have datasheets and we have communication between all
people in earth - incluiding the developers of that device.
Things are getting easier!
