Google/Yahoo actually pay the exchanges. That came up when Google started to
show real-time data in an Ajax-y form (that you can easily program against)
and some news stories at the time reported what deal Google had struck with
the NYSE etc.

Download of historical data is (AFAIK, and IANAL either) free as that is now
a 'commodity item'.  See the 'conditions of use' though, IIRC the Yahoo
historical data page has a link.  You may not be allowed to redistribute.

And timely and clean data is still a resource, and priced accordingly.

Yep.
