It's hilarious that the sketchy lawyers behind this site demand to know the “[..] details on the nature of your searches, websites visited and or purchases made [in Incognito mode]”.
I'd argue that you lost the ability to install linux on your device. You may have never made the choice to install it, but the option was yours, Sony advertised that it was an option you'd have if you gave them your money and then they took that from you after they got your cash.
That said, I would agree that the people most harmed should be the most compensated.
