Not sure what it has to do with right/left wing. Free speech should exist regardless of your economic or social views and should be protected with the force of law.
Platforms should welcome users of any background and views. Company shouldn't be able to ban someone based on their views and opinions. If user will violating T&C or the law then company should be able to remove the account.
Because the (US) right wing and libertarians are the forces first to raise a hue and cry of socialism and central planning in response to any suggestion of government oversight of corporate activities.
