I don't think there is a conflict between a right for absolute speech (on a practical level) and being held responsible for direct and foreseeable harm without a mitigating reason.
I.e. nobody can shut your mouth, or stop you from speaking, but there can still be consequences if your speech is directly aimed at unjustifiable harassment.
For instance, simply making the video available on a web site would be protected speech (no restriction on that) - assuming no other law was conflicted (copyright, etc.) But going out of one's way to push the speech to those it harms, and on services that prohibit it, creates a problem independent of the freedom to simply speak/publish.
Likewise, you can publish technical secrets you were given under a nondisclosure agreement, but will be prosecuted civilly and possibly criminally (depending on circumstances) for the damage you have done to intellectual property value.
You can claim anything you want for some product, but expect to pay for it legally if you are defrauding people.
You can publish any code you want, source or object code, but expect to pay the consequences if you are publishing code that doesn't belong to you, or violating an open source license by only publishing in one form, without providing the required form, or without proper attribution.
Etc.
For all those cases, nobody limits your speech, but direct consequences of your speech can still result in enforcement action.
