One major distinction that needs to be made is that the question of "Privacy laws" -- while relevant -- are a separate matter to the issue of contractual undertakings. The real estate industry has historically obtained written consent from its seller's and buyer's for the purpose of allowing the industry to share pertinent data within the industry and to consumer's, on an individual basis. There was not any consent sought or obtained that would condone the sharing of collected data on a broad scale, publicly, and to suggest to the contrary is: preposterous! Any suggestion now that seller's or buyer's are not entitled to have any contractual say in how the industry disseminates collected data amounts to: aggressive, self serving, enterprise. It is a lame attempt at rationalization to suggest that because data may be obtained, to some extent or another by going to a Government source, it should or could be seen a waiver against the contractual commitments within a real estate contract.
