>This is identical to how employers share salary information. For me, the difference is that using the same software to set the price based on the non-public information effectively makes it a form of collusion on setting rents, which seems analogous to the illegal practice of employees colluding to cap wages. It's not the same, I know, but has a similar negative effect in that the market is being subverted in some way. The real question for me is what, if anything, comes out of the investigation. If some new legislation prohibiting the practice comes out, I could see the big landlords simply publicizing that data to avoid any legal issues.
