I think you're confusing things slightly – I don't think idealista owns any property. They are however owned by a private equity group that invests among other things directly in real estate, which is tbf extremely common in PE.

Idealista is the lead real state listing site in spain, and has other kind of problems, but I don't think they have a say on this.
