That's the wrong calculation and assumption Elon Musk cannot guarantee that all its users will pay every month to remain verified not all people, especially those living in a third-world country have $8 to pay their monthly dues, I rather buy groceries than spend $8 monthly than keeping my Twitter account verified and besides many celebrities and rich people hate Elon for charging which was once free, now freedom of speech has a price now for Elon, I will not be a part of this.
