questions about pinterests that i dont understand

Wow, hello, so I read some peoples posts and I don't understand why people are leaving? I've had Pinterest for over a decade I think. And I ask chatgpt what to do to get more of a following. I create boards and stuff and I am part of the amazon storefront just to drive traffic? But chatgpt says create a business. But 1, Why are people leaving pinterest? 2) I dont really see any ads? maybe in the bottom? I dont think I have seen anything AI yet. So If you are still part of pinterest are you on normal pinterest or business pinterest? I'm probably confusing most of you. I'm glad i found this page though.
