Sorry to say, that is false. To adopt a child that is apart of DCFS they are even more strict.
I don't know if this holds true everywhere, at least not to the extent you mention. There's a total wreck of a person (Emily McCombs, formerly of the now-defunct garbage website xoJane) who was able to adopt "for free" through fostering in Brooklyn. She's a recovering alcoholic, drug addict, sex addict, and compulsive shopper with tons of debt who shared her fucked-up life on the Internet before and during the process. And she co-adopted her son and has joint custody with an ex-boyfriend.
