Because they are beholden to the government, corporate control over the public square has us all fucked. Today people cheer Big Tech’s ability to censor distasteful politics from the public square. Tomorrow, when “content moderation” makes civil disobedience impossible to publicize, we will lament the lack of decentralized social media.
In other words, centralized social media cements moves towards authoritarianism, but makes it very difficult to move back in the other direction, especially if attempted via the most tried and true methods in history.
The revolution won’t be televised. You won’t find it on Twitter or Douyin either. So why did anyone expect anything different? Unless the people can take back control of the public square from the corporations, democracy will crack.
Edit: consider responding with something coherent rather than downvoting and moving on
