What an amazing way to phrase "others don't like what I am saying and don't want to associate with me". The government controlling social media platforms is vastly different from a collection of companies controlling social media platforms that they built.
There's an argument that can be made about companies needing to treat their platforms as public squares depending on if they get certain protections or subsidies from the government, but as it stands its currently their property and you don't have a right to force others to broadcast your opinions
