Not an american but I would rather enshrine freedom of communication, and just explode the corporations I dont like because they suck.

Theres no "freedom to be a corporation".

In fact just end the limitation of corporate liability and let the courts sort it out.

A lot simpler than targeting a random expression of communication in protcols courts dont understand.

This would be 100% constitutional. Corporations are a legal construct, the law gave them and the law can take them away.
