Here in the UK if my car is a danger to other road users, I'm banned from using it even if the defect isn't my fault, the manufacturer has gone out of business, and the car is only a fraction of the way into its expected lifetime. Caveat emptor.
If that makes it hard for new manufacturers to enter the market, they could always form an industry association and, through some combination of source code escrow and insurance, reassure customers their products will be maintained even if the supplier goes out of business. Travel agents, window manufacturers and cavity wall insulators all have such schemes.
