Broker services?
I don't think we can stem the tide of "smart" devices but these examples of obsolescence make the case for:
(a) requiring that devices are engineered so the the smart aspects fail 'cleanly' when they lose their central coordination - for example the smart fridge displaying some nice art or being able to switch off the screen completely rather than to have to live with certificate errors or code dumps etc..
(b) requiring that smart devices can be re-pointed to alternative services - perhaps a market will grow for subscription-based central services - after all the reason these things are being wound up after a few years is they cost money and are being offered out free aside from the initial capex, right?
(c) perhaps requiring that devices talk via subscription broker services to make it easier to do (b) - would also probably help with interop where sensible.
