What is the rationale of doing this way as opposed of having these recursive servers forward the queries to an ISP DNS server?

If you use your own servers,

 

* it is one hop less

* hence it might be a bit faster

* you can not be rate limited (which appears to happen with some providers)

 

and why ask someone else if you can do it yourself.
