The issue here is that Facebook is explicitly allowing the property owners to make discriminatory housing ads. It doesn't matter how many other sources there are because publishers are also forbidden from making discriminatory ads in the law. In the end they're going to have to either stop allowing housing ads or remove any filtering for those ads that relate to a protected class (including any fine grained geographic filters too probably because those turn into a racial proxy pretty quickly) and anything that's a significant proxy for something like race.
