If Google's wrong then so is just about every ISP, caching pages for their user's speed. And there are a lot of other examples of conveniences that would be jeopardized if Google's cache was stopped. It'd be one thing if Google was somehow making it look like the actual content was theirs, or displaying out of context images or movies (their image search, I think, is worse than the page cache). They show where the page is from, and they don't alter it other than highlighting words from what I can tell.
