Prior to this era in which we're constantly online and connected, for a message to be heard it usually had to go through a professional editor at a newspaper, radio station, publishing company, or TV station. If you had an opinion you wanted to share, you had free speech but you probably didn't have a platform. Now messages are global, immediate, viral, and permanent.
Max Wang's video makes a strong case that Facebook's content policy and Zuckerberg's concern with adherence to it is a stringent ideology which lacks the flexibility to address clear cases that it should cover but doesn't. In other words it lacks good judgement.
I think it's going to be a long time before an automated system can exercise good judgement. Obviously having a professional editor review every tweet is impossible. So in the meantime, I think we will see a continual elevation of tension between people who value free speech at any cost and people who think that certain messages shouldn't be given a platform.
