Regarding the scientific issue of climate change, even Nature recently published an article admitting that models predicting catastrophic warming were wrong -- not that catastrophic warming would justify the political measures the left touts as a solution, anyway. Similarly, although Castiglione understandably credits the EPA with improving air and water quality over the past few decades, this improvement is largely to whatever degree its regulations mimicked the private property protections that were removed to cause these problems in the first place.
And regarding censorship? I'll defer to Ayn Rand:
The functionaries of the EPA are government employees, not private individuals. I would add that, among the many violations of my individual rights the EPA represents, has been its bullhorning specific answers to and interpretations regarding the scientific questions about climate change, for political purposes. I think Trump should be working on abolishing the EPA, but I'll give one cheer for him ending its improper use of my money to spread views I disagree with. (That said, I think this way of doing it is ham-fisted and looks cowardly. But telling a subordinate employee what he can and cannot say is part of an employer's purview.) As even Castiglione admits, this does not stop him or any other private citizen from continuing his "climate change" advocacy, or from pointing out the existence of the Internet Archive. Whatever you think of him, Trump is not guilty of stopping private citizens from speaking their minds: He has only deprived a vocal political faction of a tax-financed forum for their views. That is not the same thing. In fact, had he done this on principle, it would have been a win for property rights.
"Censorship" is a term pertaining only to governmental action. No private action is censorship. No private individual or agency can silence a man or suppress a publication; only the government can do so. The freedom of speech of private individuals includes the right not to agree, not to listen and not to finance one's own antagonists. [bold added]
