I think it's worth looking at how deplatforming happens here. Whether it is someone being fired or a tweet deleted or a community banned, the "cancellation" is almost always done by a company. Companies operate more like amoral optimization functions than they do moral beings. In this case, the incentive driving them is bad press...companies are terrified of being on the wrong end of a media cycle. The driver of bad press, in an era where tweets are constantly used as primary sources in news articles, is social media. The result of all this is that speech in society is now partially governed by twitter outrage. There is some benefit to this, as the loudest voices on twitter are willing to stand up to power (as opposed to letting the elites determine who should be fired for speaking out on their own), but it's also horrifying to think that twitter anger is, to a growing degree, governing speech in our society and setting the standard for right and wrong. Twitter mobs are incapable of handling nuance, and yet productive policy discussions can't happen without it. That's a pretty serious problem.
