Fraud is profiting by deception/illegal means.

Profiting by deception is why marketing even exists tbh. Nobody's plastering ads that outline products in factual unbiased way, it's all just a hair above what the law defines as actual fraud. Except one every so often that deliberately breaks the convention and is often even more likely to be deceptive by fooling people into thinking it's honest.

Name the industry which is not profiting by deception at large?

There’s nothing sad about it. This world is a foul sty, and seeing it through pink eyewear thinking it’s all roses and unicorns - is actually sad.

Because truth inevitably hits everyone.
