Marco Arment:

The race to the bottom. Deceptive low-now, high-later pricing. Scam and clone apps. Shallow apps with little craftsmanship that succeed, but many high-quality apps unable to command a sustainable price.

The “top” list encourages all of these — we’d still have them without the list, but to a substantially lesser degree.
