I think that to some people this could seem misleading and/or incorrect.
8. People manager As opposed to "Goldfish supervisor?" Seriously, this is a "try not to offend anyone term," that makes managers of people and non-people (whatever that is) feel less like managers or people and more like guppies.
"Manager" is a very wide term. You can manage processes, you can manage inventories, you can manage people, you can manage documents. Is a document manager a people manager? No.
5. Take Away You take away food in a paper bag with a clown on it. Period.
Sometimes "What's the take-away from this?" can be a good quick synonym for "What are the important conclusions and insights we should get from this?" You might dislike it, but it's hardly ban-worthy.
Certainly, some of the examples there are pretty annoying, but I don't get the whole "words to ban" thing... seems like a pretty weak article for a publication by a prestigious university.
