They consider their data to be theirs, even though they published it on the internet. They consider your data (your personal integrity) to be theirs as well, because how can you assume personal integrity when you are surfing the internet?
I have high hopes that the judicial system some time not too far from now will realize that since the law should be a reflection of the current moral standings it will always be behind, trying to catch up with us and that those who break the law while not breaking the current moral standings are still "good citizens" unworthy of prison or fines.
I guess Google won this iteration of the internet because of the double-standars site owners stand by, to allow Google to scrape anything while hindering any competitors from doing the same. There will only be a true competitor to Google when we in the next iteration of the internet realize that searching vast amounts of data (the internet) is a solved problem, that anyone can do as good a job as Google, and move on to the next quirk, around wich there will be competition, and in the end that quirk will be solved, we'll have a winner, signaling that is it time to move on to the next iteration.
