I'm not sure. Look at "smart" TVs. Their prices continue to go down. Why? They are heavily subsidized by all of the analytics they earn from the data you provide them. By lowering the price, it makes it easier to sell to more and more people. Raising the prices does not.

Not sure of the number of units sold comparing dishwashers vs TVs, so maybe there's not enough volume in dishwasher? Also, I can only imagine the analytics data from TV viewing is much more informative/beneficial than how many times someone washes dishes.
