You're right. That's what I was saying pretty much in my post.
I don't think it's anything to get too worried about, if you are. After all, before the Internet, what did we have as source of archived information? Microfilm and microfishe (sp?) at the library. We still have that today. Just no one likes to do that, becuase it's a lot easier to just sit at one's computer in 5 day old sweatpants and shirts, surfing the net for what you want.
Don't get me wrong, there are political (and probably to a lesser degree financial) motivations behind this, imo. But I don't think we have to worry about information being kept from us. If we really want something, we'll just have to get our lazy a$$es up off the computer chair, and get to the library, and archive it the "old fashioned way". hehe
The real problem comes when they start keeping archived articles away from anyone, at any time. That's something to watch out for.
Or they modify articles in the archive without telling anyone or leaving any evidence that the "archived" story is not the original version.
