I propose 'sensible' limits on what you can say, and when, and to whom, and how you do it. That's all. You should have a license proving your ability to speak intelligently and reasonably, and be permitted to do so in some approved forums with professional moderators to ensure compliance.
That's all I ask for YOU.
