People do use big words because they think if they show they are intelligent, people are more likely to believe their answer. But if you are wrong, you are wrong. Doesn't matter how intelligent you are.
Sometimes people use big words because there's a subtle distinction between the word they are using a smaller word. The subtlety may be lost on people who doesn't understand it but if we pandered to this and always used small words, subtlety would be lost on everyone. What kind of person says, "Let's find the stupidest person in the world and then all get down to his/her level?"
There's nothing wrong with striving to improve, and there's no merit in blaming people who have. As if it's some bad thing.
