I don't like censorship, but I have a hard time criticizing those actions.
We are in a hyper-political environment, where your company is going to be judged by one group or another for any action or inaction. So if you're protecting far right nuts, your left side is going to drop you. In a very real sense, protecting 8chan or Daily Stormer is a company deciding to solely make itself palatable to supporters of those sites, at the expense of basically... all your other customers.
No company that wants to be successful is going to stand in defense of a customer or two that's known as a source of terrorism and violence.
Given that Prince studied law in Harvard he is way more knowledgeable and aware than average CEO.
Who are you thinking of when you talk about censorship?
IBM, VW, Deutsche Bank, etc.
