I'm remarking that it's hard to me to take seriously a claim that Apple has these mystical standards that must be met and that they're just trying to "cultivate a quality ecosystem".
Seriously, download some of those apps. At least two have -very low- quality images (they look like obviously massively resized, highly pixellated images) that get a weird red glow that's more akin to image corruption than a 'highlight' when you touch the screen to generate a highly unrealistic fart noise (in the singular - just one simple noise, not even a range).
