I guess we could find some funding for Parlor. Then crush Twitter with the iron fist of capitalism.
There used to be a thing called Usenet, where everybody just said what was on their minds, and we managed to live through the free speech.
Now we have Twitter and Facebook, which have become de facto modes of communication for a majority (not me) of not just Americans, but global inhabitants. Both platforms decide for their users what is and is not free speech. If they were small entities like APS, who cares? You just go to another forum. When they have become the main sources of communication and news for people though, they have some responsibility for the fallout of their biased policies.
They also have little reason to change, as long as people continue to default to them. As long as they continue to fall ass backwards into giant pools of money generated by selling the PII of their users, there is no big incentive for them to do anything but say, FU.
