Whenever someone brings up Twitter's political and corporate biases, people say stuff like "Freedom of speech doesn't equal freedom from consequences!" and "Twitter is a private company and are allowed to enforce their own rules!"

The issue libertarians have isn't that big tech billionaires own anything, it's that the specific ones that own them right now are using them in authoritarian ways, which I don't know if you've taken a look at a political compass before but those two are on opposite ends of the axis.
