It is also heavily regulated in certain circumstances. Revealing classified materials is heavily restricted. The SEC regulates statements by companies or their representatives that affect investor behavior and stock valuation. The FDA regulates speech as it concerns the marketing of foods, drugs, cosmetics, and medical devices.
These are all good things to regulate and I’m sure they are just a sample of restrictions on free speech.
In other words, “Free Speech” is a lie told by someone who’s trying to sell you something.
