Well, the basic idea of it is not so bad. A business generally wants to keep their customers happy and care for their reputation, so telling a business when we’re unhappy and influencing their reputation is the feedback mechanism we have at our disposal.

The important thing is how we go about it, and whether their reputation remains reflective of their actions, or we try and make it worse than it ought to be. We can’t say for certain the author of the message was going to do the latter, but it does not inspire good faith.

It's textbook extortion.

Telling a business we're going to fuck you up unless you send our friends work, even by implication, is literally extortion.
