It might be. RealPage's definitely is because they've clearly accrued market power in order to control pricing. In Redfin's case it seems like more of a marketing gimmick, but if you could prove it had a meaningful effect on driving prices up, then yes, the FTC should order its' removal.

It depends? Playing moneyball (i.e. charging the maximum the market will bear without a serious, violent response) with a necessity like rent should be illegal, and many of these tools seem designed to do that using market power, which is explicitly illegal. If the tool just gave some local averages based on things like amenities, that might be ok.
