PSA: The First Amendment does not insulate companies from anticompetition law.
Imagine a world in which every time a business released a deceptive ad (e.g. claiming their herbal cure cures diabetes in 24-hours!!!) the company could shield itself from FTC litigation by claiming their lies are fully protected by the First Amendment. It’s absurd.
The fact that one is speaking does not a magical shield against all legal liability make.
