If you are a company that offers something, you are responsible for complying with regulations regarding that thing. If you sell meat, you are responsible for ensuring it is not rotten. If you manufacture or sell toys, it is your responsibility to ensure that they do not contain toxic substances nor small parts that are easy to swallow. And if you run a search engine, you have to ensure not to infringe on the privacy rights of your customers. As with any other company, the costs for this are costs you are going to have to calculate with when considering how to do business, and what kinds of business models are viable for you.
I have no idea where technology companies, especially U.S. based ones, get this idea that they should be allowed to infringe upon rights and regulations wherever it gets in the way of doing business simply because what they do is somehow new and cool. That's not how that works. Mercedes-Benz cannot make a car that doesn't follow road safety regulations, even though that may allow for cool things and cheaper cars. And in the same vein, Facebook cannot simply store whatever data they please and sell it to whomever, and Google cannot simply index all things until the end of times, even if all of these things would be very useful for them and possibly allow for neat features - because there are regulations that protect the common interest, which they have to follow.
