If you agree with that, then my argument is that over the long term, the amount of money a company can spend on marketing is related to the amount of money they make per customer. If you sell a $1 product, you can not afford ads that cost $3 per conversion. If you sell a $30,000 product, you can afford pretty expensive ads. Of course n the short term this can get skewed. A company can dump money into ads in an unsustainable way, but that always seems to correct itself (see: Fab).
Given that a product is generally priced to some extent related to its value, the higher value products will have higher revenue per user, which will allow them to bid more for advertising.
That means we are more likely to see these ads bought by companies that make decent money on their apps. I'd love to see more high quality apps at the top of the listings, and I'd also love to be able to promote my (hopefully) high LTV apps at the top of the listings.
