Ok but now explain why there are tons of absolute trash vibe coded apps that barely do anything in the app store?

First, I am not trusting them at face value. They are building a copycat of Serum and most likely could be doing some level of vibe-coding themselves.

Second, to your point, say we trusted them, it's a chicken or the egg problem. After all the trash entered the space it became flagged and a scale/moderation issue.

The larger problem is the bad actors.
