Actually - usually it's requiring others to promote, pay for or echo their speech.

I'm free to speak, and make you speak what I want, and pay for my speech, but YOU can't make me say things I don't want to.

Huh? Stand on a soapbox. Get a group together to promote your ideas. You can do all of this without going to jail, but google doesn't have to pay huge amounts to pump out your BS.
