Has there been any successful app stores since the mobile app stores, which made developers fortunes selling fart apps, thus making it highly appealing for others to try and chase the same?

Every one I can think of since gets a bit of initial interest hoping to relive the mobile app store days, but interest wanes quickly when they realize that nobody wants to buy fart apps anymore. That ship sailed a long time ago.

And ChatGPT apps are in a worse position as it doesn't even have a direct monetization strategy. It suggests that maybe you can send users to your website to buy products, but they admit that they don't really know what monetization should look like...

I can certainly think of some organizations that fit into that bucket. I can also name organizations that are hyper controlling and micromanage every aspect of the interaction with their core products and services because they value consistency above all else.

I wonder if we'll have a situation where out of two competing organizations only one is elected to use this and the other one staunchly opposes. That will be telling.

Atlas being created is kinda the shot across the bow. You can integrate with us willingly, or we'll hook into your web apps anyways. One retains at least some control. Same outcome as Disney's deal with Sora.
