Way back it was not so uncommon that companies buying software had access to the sources. When they did not have access to the sources and the machine code was supplied by a small vendor there were escrow agreements for the source just in case the vendor went out of business or died.

Abandoned IoT devices if there are few of them are an issue for the consumer and they should be enabled to at least help themselves or hire help. Abandoned IoT devices if they are in larger numbers can pose a threat to the network and one may consider what could be done about those. Abandoned IoT devices also are an economic burden as they cause a premature loss of value of investments of consumers and investors. Worse are way too many horror stories out there of critical infrastructure running on outdated platforms. These devices were bought at a time where computers were rare. If we extrapolate 15 years from now based on the experience we have today - we will not see accumulated economic loss but disasters too.
