I think you might be conflating what are the most profitable social media business models with what people actually want. It's the difference between a lucrative something that addicts or traps, and something people genuinely enjoy or believe in.

I think there is a growing amount of people who want to get out of the social media Skinner box, and there are also growing amounts of people who believe in new and alternative technology like this.

Sure, these platforms might not appeal to someone who uses Facebook like you would a slot machine, but I know plenty of non-tech people who use things like Linux, Firefox, Android/LineageOS/GrapheneOS, etc for moral and ideologically appealing reasons.
