If you make a habit of shitting in the dining rooms, you'll likely find yourself banned from all the restaurants eventually.
Sorry, was that Twitter? Or Facebook?
It's kinda hard to argue it's a monopoly when I can't figure out which one you're referring to and you're saying "Twitter and Facebook".
Meanwhile, this is why the USPS isn't a great comparison: https://en.wikipedia.org/wiki/Private_Express_Statutes
1. A government organization
2. An essential service
3. A de facto monopoly in many rural areas that are not profitable for private companies to serve.
Facebook/Twitter are none of these things.
HN: Facebook and Twitter are a stupid, pointless waste of time and you should delete your account and leave those platforms.
Also HN: Facebook and Twitter are essential services and banning people from Facebook and Twitter is a fundamental violation of their human rights.
