I agree wholeheartedly: the "right to free speech" is not the same as a "right to be heard", but we have managed to conflate the two with all of this "free amplification", as you describe; there is a big difference between someone getting to say something to their followers and that content being broadcast and even recommended by Twitter to random people. I personally believe that if a website has a recommendation algorithm that should be considered an editorial decision they are making and they should be liable for the content they recommend (and much more so than they are today: the same level of standard we hold a newspaper to should apply); but, if a user merely posts something and people have to actively choose to follow the poster, then that's on them (as the website is acting as a utility connecting consenting parties). Doing it like this (which might even be the status quo of the law if Section 230 is repealed, btw) changes what kinds of apps can be built and what businesses models are viable "at scale", but almost certainly for the better: apps that work like how Instagram used to--where you just saw content from exactly who you followed in the order they posted it... something many (if not maybe even most) users preferred but which was clearly less profitable for Facebook--seem like they should be fine and you should get to post whatever you want to the people who opted in to hear what you had to say. People who generally like recommendation systems try to defend all of their algorithmic amplification, and then the sometimes-arbitrary-feeling censorship seemingly required to make them universally viable, but here we see Twitter taking the ridiculously extreme position to even block private messages... the regulatory fallout of this political decision is going to be fascinating to watch.
