That site in particular is a perfect illustration of the problem with the Ultima games. They are legally available for free, but not on that website, only on those websites with the specific permissions to distribute the free version.
Such is one of the many problems with our society, our economic model, and I agree.
We, as citizens, have an obligation to try and encourage movement towards improvement in that society.
In Australia it is techincally illegal to record a show with a VCR. Crazy, I know, yet it is a law that is largely ignored (or at least was back when VCRs were still used). In Australia it is also illegal, technically, to congregate publically in groups of 3 or more. I'm sure we can all think of similar laws in our own countries that are outdated, and eventually ignored by citizens and law enforcement alike.
The famous story in American history with an African American woman refusing to comply with racist segregation laws on the bus is a prime example of how this process can be hastened by citizens who believe in a more just society.
The fine balance between encouraging new cultural creativity and stifling it is one philosophically precarious, I know, which is why I am such a loyal customer of gog.com and the changes and ideals they represent. Yet if we do not have the financial or political resources to make these changes, we must at least live our lives according to them, and historically speaking society does indeed follow. If for no other reason than the temporary financial gains to be made in the short term, eventually the moral argument is recognised and accepted, as it is today by most everyone, just not those with a financial investment in stifling that process. :)
You bring up a good point about corporate image, yet I think your anxiety is exaggerated. GOG is firmly established, and if EA should somehow prefer to not make money from selling Ultima, then it is their loss only, as the public does indeed have access to other alternatives. But I'm considering what you said, and shall have to decide about posting such links in the future. If any moderators wish it removed I shall gladly do so, as I would not want what exists here to degenerate anymore than the rest of us :)
