Abandoned software should be, under no obligation by law, to be released to the public since abandoned or not, the rights should belong to its creator(s) as is with real estate. Additionally, abandoned software may contain serious bugs, or security vulnerabilities placing users at risk. If this was required by law to be released to the public, there must be some precedent for users to be allowed to be exposed to these risks.

Yes, it should in fact, copyright is not lost for abandonware, and that distributing or preserving it can still be illegal, but legality depends on licensing and permission. Now, in the capitalistic society we live in, what credit does the owner, under your system attain for creating the software in the first place? And as for your question "Should property rights mean anything when the owner has locked the door and walked away?", My answer is yes, and strongly yes, since as ownership is independent of usage, and if there was such a law, how would you enforce it? Time limit? But what if the developers needed a break due to life's struggles and challenges? Stating that it is abandoned does no good either since developers may even return to their old project, so I have answered your question and I beseech for you to answer mine, which is, what credit does the owner retain for building the original software, and going to the trouble of releasing all the dependencies and warnings?

Developers should maintain the right to take as much of a break as they wish or are allowed by their bosses, not some arbitrary number set by the government because now they are forced to file every time something does come up, and in practice, this is the case. Software can experience delays, that is reality. Now, my opponent still has not answered my question, in does their system provide credit that the owner retains for building the original software, and going to the trouble of releasing all the dependencies and warnings? Now whilst their proposal contains minimal ambiguity, this only increases the hassle. Now they believe that the mere fact that the disc exists should allow fans to assume control of it. But do we not see the problem? The property was never communal to begin with. Anytime a house is being rent, its ownership is never transferred, and if the tenant is evicted, the house still stands, but should people be reverse-engineering it? And if the fanbase was so large, would there not be continued support due to product popularity? Please, answer my questions.

Delays in software often reach periods of greater than 5 years, and the opponent wants you to believe that, after this arbitrary duration, ownership should be revoked and released to the public. Please remember that modern software is built on complex trees of proprietary third-party libraries, middleware, and licensed software engines. Mandating the public release of "abandoned" code forces companies to illegally expose or breach third-party IP that isn't even theirs to give away. Releasing unmaintained legacy source code creates a free blueprint for active cybercriminals to find zero-day vulnerabilities in shared libraries that live on in modern, active software systems and even with the opponent's suggestion of warnings, it may prove difficult or even impossible for the developer to release every possible security issue. Furthermore, creators already have voluntary options (Open Source licenses, Creative Commons, or official archive exemptions) if they wish to release old code. Forcing it by law strips creators of property autonomy and penalizes innovation.
