Would you rather have 3 big websites instead of indexed web?
That's what we already have, I'd you need to find stuff by doing site specific googles, both google & that site have failed.
The web is dead, it's been dead for a while, now is the time to build something new in it's wake that rather than depending on closed source algorithms, indexing 3 big websites, we could just search the 3 big websites directly.
