>We can imagine a social media that doesn't play games with the "attention economy", trying to "increase retention"

A social network where no one is there is not that valuable. Incentivizing people to "socialize" more has exponential value to a social network.

>As a result, these major companies no longer need to create better products so that you will use them instead of a competitor,

I feel like this person is regurgitating old arguments. With the recent AI boom, it should be obvious that companies are still trying to build better products. And it is fully possible for new players like OpenAI to get a billion users.
