This could be solved with a state-mandated escrow service. When selling anything that relies on network services, companies should be forced to provide server and client source code to an authority, which will keep it in escrow indefinitely. The company is then required to renew their "IP lock" every X weeks/months; if they fail to do so, the code is made publicly available (maybe for a small fee, to cover operational costs). Extra red tape? Maybe. A perfect system? Probably not, as companies would likely fail to upload updates after the initial market debut; and probably someone would occasionally forget to renew locks on products they still sell. Still better than the terrible status quo? For sure.
