I'd have to look more but maybe running a cache isn't dead simple. I can imagine that the benefits of manipulating what's in the cache either adding or removing would be very high. Google and the others are private companies so they're not required to do everything in the public view. A public cache wouldn't be able - indeed shouldn't - to play cat and mouse games with potential opponents. I suspect most of the games played require not explaining exactly what you're doing.
