sorry but its not that cut and dried. if it were many games that are more than 4 years old would be released under a GNU...as it is 99% of them aren't. There are legal precedents where an intellectual property can be forfeited simply due to a company's lack of maintaining a financial interest in said IP. Its a similar legal loophole that property owners can fall victim to. Let a neighbor store his shit on your property which borders his and he can petition the court to have it turned over to him (it's not that simple of course but thats the gist of it). It's fucked up but it happens. Once again we can thank our friend, the Attorney, for the state of things.
I can take a crack at you retarded post, in reverse. As convenient it is for you to vilify lawyers, you clearly are not one since you mix up so many issues, so perhaps you should stick to your day job.
The issue you refer to in terms of real property is adverse possession, who requirements are - most state require that the possession be open, visible, or obvious so that the record owner (the owner shown by public records) can recognize the possibility of losing the land. Most states have a statutes of limitations so that adverse possession must last for the time required by the statute, also known as limitation title. Historically, adverse possession lawsuits have been filed involved a family relationship between the claimants, and permissive use among close family members.
So if some stranger/neighbor "stores his shit on your property" as you put it, means nothing. It has to be non-permissive use - that is, you never gave any such permission, it has to be out in the open, not hidden, and finally, depending on the state, has to be for a number of years. If you gave permission to your neighbor to store his stuff does not mean he can now claim the land.
As it pertains to intellectual property, rights to such property are created under the Constitution of the US, under Art. 1, Sec. 8, Clause 8. And is it pertains to your post about games, it pertains to copyright law, which falls under 17 U.S.C. Section 102 (Copyright Act).
When you are referring to intellectual property being forfeited simply due to a company's lack of maintaining a financial interest in said IP, you are referring to abandonment. Abandonment of Invention: To relinquish rights in an invention. An invention is considered to be abandoned, if within a reasonable time after the invention is completed, no actions are taken to make the invention publicly known. Abandonment pertains mainly to patents and trademarks, not copyrights.
In the domain of copyright, abandonment is recognized as the explicit release of material by a copyright holder into the public domain. However, statutory abandonment is a relatively unclear area of copyright law and the more common approach is to license work under a scheme that provides for public use rather than strictly abandoning copyright, in this case, the GNU license you reference.
You cannot make anything fool-proof. The fools are too inventive
