(Incidentally, someday a piracy site like that could serve up a browser zero-day, and pwn a large percentage of US tech companies. Without ever having needed to go to the trouble to develop their own content that would attract such a large audience of tech workers on work machines.)
These other archive.* services seem to be used mainly for piracy. I don't know whether that's the intent, but that's the only use of them I recall seeing.
I think conflating the two categories of services might put archive.org at risk.
