Buy information like this to better understand your potential victims = maximum profit. Been scammed once? you'll probably be contacted again - it's the equivalent to responding to spam mail. Once they get a bite, they all come running.
Successful con-artists will sell victims information on to other scammers, to bleed them dry even more. The amount they've stolen from you determines the price of your personal info.
People are sheep and likely won't pay any attention to this at all. Sweep it under the rug till it's too late.
In the end, big business (Legal or not, no difference) is interested in one thing: Profit. None can be trusted, no matter how clean their track record. Eventually, management changes.
I must agree with your closing statement, big companies will trample over anyone to make an extra buck.
