> Often miscommunication today happens not because the sender needs to dumb it down for the receiver, but that the sender is too lazy to use all the words necessary for full communication to the recipient.

I think both are extremely common.

On social media, what we see all the time is people getting absolutely outraged about things that none ever said and they just chose to project onto others.

I can't blame the original speaker for this because there is no way that you can phrase anything that will prevent people to distort it into whatever they wish.
