Although this is a shame it is yet another sign (for me) that the 'Internet of Things' is going to be DoA if we have to also rely on them for a backend cloud service. Most of these devices could be run in a completely decentralised way, such that if the company goes under, your device is hardly affected. e.g. I don't expect my light switches to stop working if the parent company gets acquired or shuts down.

There are real challenges to making distributed systems easier to build but I'm working with others on that c.f http://nymote.org and http://openmirage.org.
