I have seen this with my own eyes. Facebook social media is very popular in our country and earlier those who were big content creators mostly depended on monetization, that is, on the income that would come from ads on the platform. But now I can see that most of the content creators are focusing on their own businesses. The main reason for this is that they have a good fan base and they trust them. Based on this, if they release a product in the market and show it as organic, then their sales are several times higher than that of a regular businessman. But yes, if the quality of the product is not good, then that business does not survive for a long time. However, those who I have seen succeed have generated a good amount of earnings in about a year.
Something happened to Facebook creators from your region that is why. For many years, Facebook wasn't monetized in some regions. When they finally gave them opportunity for everyone, many creators abused the privilege with reposted videos and create slop contests to milk the creators program and they have to forcefully closed the program. That's why many of them are back to street looking for where they can get work again.
X launch its creator program about 2 years ago, a lot of people were earning what the couldn't make from their business in 2 weeks a verified account was making what's some business people couldn't make in a year but when they find out that people were abusing it, they stopped it completely. To earn now on X, you have to post original content and there are other rules which you must satisfy. These made it hard for many to make money from the program.
