The point I was making is that CL are increasing the utility of their service by using Google/Yahoo to provide specific maps of property locations. The distinction is that the relevant data curation (property locations) is done by CL, not the mapping providers.
I also noted that API usage would have been paid (or at least licensed), so in that sense, CL are (legitimately) freeloading on Google and Yahoo. While the argument could be made that CL are sending traffic to these sites, that same argument would apply to Padmapper.
