Jargon hurts your communications. I found a great quote about this in Simple: Conquering the Crisis of Complexity by Alan Siegel and Irene Etzkorn.
Here it is:
To connect with people, you have to speak their language. The use of jargon represents a decision on the part of companies and governments to speak in a language that they understand and you don’t.
Jargon can lead to your messages becoming “lost in translation,” as the authors say.
