The case before the Supreme Court about the Hillary slam “movie” seems to be about how much they can be regulated.
I think they can be totally regulated in every way, including having their charters rescinded for any reason.
I think the Constitution protects people but doesn’t give any rights whatever to corporations, that those are granted by the issuing government, and thus vary a lot, and that the feds can overrule all states in matters of broadcasting.
Say who? The SCOTUS ruled many moons ago that corporations are, in fact, persons, and therefore have requisite Constitutional protections available to them.
As a matter of fact, The Perfect Master elucidated on this concept.
While I would agree that if the legislature can revoke the right for corporations to exist, then they can create them only for very specified purposes. However the Courts have assumed for over a 100 years that corporations are full fledged persons for legal purposes, and the way the law works, that is not going to be overturned.
