Except that goes directly against Elon's supposed goal of creating a "town hall" for the greater good of humanity.
It doesn't matter if 10,000 blue ticks are responding, if even 100 non-blue-tick messages get drowned out. And it doesn't matter if you consider those 100 users to be riff-raff or cheapskates and therefore unworthy of having their voices heard.
A town hall is meant to a place where everyone can voice their opinions and everyone else can contribute to the discussion. Prioritising certain voices over others is contradictory to that idea. Hence, Elon's idea of a "town hall" promoting "free speech" can only work if everyone on the platform pays (which will never happen, not because people are cheapskates but because many people have more important things to do with their minimum-wage salaries), or the voices of the people who are paying aren't favoured in any way, otherwise everyone on the platform isn't on equal footing, and there is no "town hall" in effect.
Of course its his $44billion and his platform now, so he can do whatever he likes with it and people are free to leave if they don't like his decisions... but he shouldn't be deluded into thinking that he's creating a town hall in that case.
You can argue that the riff-raff who can't afford $8 a month on a twitter account don't deserve to be leeching of the platform for free, and that's also a valid viewpoint, but then you also shouldn't delude yourself that Elon is creating some sort of free speech town hall, because he's not. He's then created a service for people who can afford it, not for the greater good of humanity.
