With "wrong opinion" do you mean inciting hatred and violence, and spreading misinformation?
Because by that logic, we should also allow ISIS, Al-Qaeda et al. to do their thing.
Outside of these "wrong" opinions, parent commenter is pretty accurate. I've seen and heard of people launching a website in less than a day.
Let's not forget that freedom of speech does not give you freedom from consequences. AWS, Twitter, Google, Apple and everyone else has no obligation to give you a platform, especially when it looks bad on them, or it goes against their ahem morals (or rather: the employee's morals). Just like I, as an equal citizen, have no reason to hear you out or to spread your message, if I don't like your message.
