Vogons forum is strict in this matter because, Vogons which started as a support forum to help run old games on new systems and dosbox, has to be protected from being dragged into legal issues arising from "abandonware" usage, because it's main purpose is to help run (mostly) Dos games on new systems, and "abandonware" is usually referred to the Dos games that are involved. Hypothetically speaking, it's easy for the SPA to target Vogons, when they see "abandonware" games are thriving because of the Vogons community which "helped them run abandonware games", since after all, this is THE site dedicated for running Very Old Games On New Systems.
We all have our own opinions, the thoughts of rights and wrongs of "abandoned softwares", etc., but the discussion about abandonware is not done here, so as not to trouble the Administrator and Moderators with unnecessary issues.
