Private companies in the US have always had the right to refuse a customer anytime, for any reason. No shirt, no shoes, no service. Should a social media company be treated differently?
We need careful consideration on both sides, and it's disingenuous to pretend that they're simply a private business and that we can treat them as if they aren't effectively virtual public squares that dwarf anything in the real world in scale and reach.
Recognized public squares (eg the National Mall) are protected by regulation. Is that really what people want for Youtube?
McDonalds has more than 10X the revenue of its closest competitor (KFC). Should they be prohibited from kicking out a customer who is causing a nuisance?
