“a software company called RealPage is being sued by the Department of Justice for using an algorithm that suggests rent prices to corporate landlords. The DOJ argues that its algorithm has driven rents higher, and constitutes an illegal information sharing scheme. That is, competitors (the landlords) who would otherwise be acting independently, have exchanged “nonpublic, competitively sensitive data” to the detriment of renters who don’t have access to such knowledge.”
