Why do they wish to destroy information that can be useful?
Because it is from the mid 90s, and they are paying to host something that has had no bearing on anything they have sold in pretty much two decades at the least.
It is nice when you get this sort of resource hanging around for decades but honestly, a _lot_ of the people using it these days never bought a new Mac in their entire life and
some of them
really hate what Apple is now and do not intend on buying a new Mac yet still want support for their old machine that they found in dad's closet or on ebay cheap or curbside.
Hosting files costs money. I suppose you could argue that "they are already hosting files and these take up 0.001% of their resources". On the other hand catering to 0.001% is not always good for the company's time/bottom line, etc, despite being good for PR.
Apple does not actually owe you this resource. Most of you are not Apple's target market either no matter what some people might want to think.
Please keep in mind that this is a generalization, I am not singling out any specific people. Just commenting on what I see.
And do not get me wrong, I like when I can go to a company's website and get ancient drivers/docs.
