What happened to "do no evil."
But seriously, only focusing on the search engine side, Google really doesn't have any responsibility to site owners, though they make them jump through hoops to get higher ranking. They are, after all, a for profit business which built themselves on drawing everyone in with whatever offers/products/gimmicks and, once big enough (too big to fail), changed the rules. That being said, ultimately, we brought this upon ourselves by truly focusing on one search engine rather than allowing for diversity.
