First of all, we all accepted but few read over the user end license agreements for the software we use - including games. RE was specifically not permitted.
Copyright ownership does not end if a company does not produce further updates or similar titles.
Google was undergoing a class action law suit representing authors (I am one of them) for displaying book contents without permission. They settled out of court and have to pay millions.
Each of us has our own opinion about the right of it, but accept that it is basically illegal to RE software for any reason. Just about every program end-user license I have encountered indicates that ownership of the program remains with the maker and the license is to use it.
That should kick up some dust in the forum !
