This would be hard to legally call extortion, since consumers are free to do business with who they please, and there is a strong history of boycott activity. Also if it were illegal, then many negotiating tactics become extortion. Is threatening to leave a company unless you get a raise now illegal extortion? Is demanding a lower cable bill or else you'll go to a competitor now illegal extortion?

I would consider these more ultimatums than extortion. Also extortion always includes quid pro quo, but not all quid pro quo is illegal. Context matters.

That freedom, like many others, is limited. You may also be dismayed to find that you aren't free to tell someone that you will do business with her on the condition that she sleeps with you. This is quid pro quo harassment.

I'm not dismayed at all, and would appreciate it if you could refrain from painting pictures of what you think my state of mind might be. Thanks.

Are you saying that I am breaking the law by telling a company that I will not do business with them as long as they employ some person? Just to head off future misunderstandings on my part I'd like to get this clear first.

It was a hypothetical. I wasn't speaking about you specifically. Anyway, I've explained in another thread as simply as I'm able. Good luck on your educational endeavors.
