It's possible that rents would be dropping more if this platform were not used by landlords. That isn't to say it should be illegal or is unethical, just to say that the fact that rents are dropping doesn't mean this platform isn't having an effect everywhere it's used.

I think it's entirely possible that it does have a small effect. A percentage point or two.

And a percentage point or two across thousands of people renting adds up to real money they are helping to skim. I don't see any downside to going after them.

That said, no, one company is not to blame for soaring rental prices across the US. It's mostly supply and demand.
