It's a fair point to say that you spent money on something based on statements that were not true. Technically, Sony's statements were not true!
However. This isn't really a situation where anyone got duped into buying a bad product and lost money because of it. For example if you bought an Ouya based on some claim and were left with a paperweight you can't do anything with.
You can easily resell your PS5 for more than MSRP. So, if you want to reverse your purchasing decision, you can simply sell it and then thank Sony's lie for the yield on your investment.
I sold my ouya for full price a year after it came out as people used it for Android development.
