That doesn't change the point that for most people getting fired from a job is serious life damage that ought not to be trivialized as "angry tweeters". A few outlier examples don't prove otherwise, losing a TV show isn't the same thing, etc. It seems to me that you're minimizing the significance of this development. There's also the fact that ostracization is traumatic for most people.
What I said about prisons was unclear, sorry. I was trying to imagine what the next escalatory step would be after getting someone fired. Perhaps it would be putting them in prison. If so, someone would be making the same argument again: it's not as if their life was destroyed just because a few angry tweeters got them jailed, they'll get out soon enough, and so on. The point is that there are degrees of harm. Just because it could be worse does not prove that harm isn't severe.
