Maybe so but this is far worse than that.
This is actual coordination, like just literal price fixing. For example the software requires users to actively ask for an override if they deviate from the recommendation. It's pretty literally a "trust" in the old school sense, of some kind of organization that coordinates actors across a sector.
Price discovery is probably also already illegal, but there's at least one layer removed, in the sense that competitors are sharing price data with each other and using the same algorithmic tools but coming to their own conclusions.
My view is that also is and should be illegal, and I hope you're right that the whole approach will be under scrutiny right now.
But the rent one is even more clear cut, it's almost impossible to justify unless you're using motivated reasoning to pretend that it's somehow different if you do it in a SaaS platform instead of a conference call or in a smoke filled room.
