In response, she handcuffed herself to Twitter's front door in New York City to protest her ban and only recently was cut free by New York City police and arrested.
I don't agree with Twitter's banning operations. However, as far as I am concerned, Twitter is a private company and should be free to run their business however they choose.
That said, as I have previously pointed out, bans don't work (See: Can Ideas Be Blocked?). The establishment will always try to silence the outliers but it doesn't work. They fail to understand the true and deep nature of second-hand dealers in ideas, which was outlined by Hayek.
