I'm not being flip when I say : the same thing that happens when other companies go bankrupt. They're products may or may not work anymore, may or may not be serviceable anymore, may decline in value to zero (or not), returns for defects not possible and so on...
Different people - early vs late adopters - will have different tolerances for these things.

Does your home have a thermostat? Does your car have an engine control system, automatic heating and cooling system? Does your lawn-mower have a mechanical throttle governor?
I am being a little flip in this last part - obviously you're not defining those as "smart things" but talking more about the modern "internet of shit" definition ..but my point is "smart things" today are different from what they were in years past and will certainly be different tomorrow..
