This is the “if you don’t like it, go build your own multi-billion dollar monopoly internet service” argument. And then it’s just one more step to call for public-private partnerships in combatting “misinformation.”
It's literally trivial to have your own twitter/facebook/youtube analog. You can in turn spread information about its existence through exciting means like email.
You aren't entitled to an audience of hundreds of millions and indeed have never in the history of free speech been entitled to such.
When taxpayer-funded officials are telling private companies what to censor, your argument falls on its face. It has nothing to do with how hard it is to build a website.
I'm not aware of anything being censored other than spam and other obvious breaches of TOS. Not being algorithmically promoted to like minded weirdos isn't the same as being censored.
You have no legal right to an exact placement in search results or in people's feeds. Censored means your content is obviated, deleted, removed.
