Personally, I struggle with the idea that scientists working for the federal government have to report to or be muzzled by the current administration. I see these people as working for the country not for the administration but I'm naive and optimistic in general so I'm sure many people will point out that it would be a crazy way to run a country.
In the Canadian case, scientist needed to request permission to attend conferences months in advance and, from what I understand, if there was the least chance of bad press coverage from the scientific results being presented, then the person was not allowed to attend. I believe there was a similar muzzling of attempts to publish in peer-reviewed papers. That sort of thing is clearly not acceptable behaviour for a government administration. Government organizations like the EPA are not companies trying to maximize profit by selling a widget, they are researchers and regulators trying to determine the best path for everyone in the country with respect to economics, health, and environment.
The US should not put up with any, even a temporary form of such censorship of the parts of the government that are doing scientific research and environmental stewardship. There should be another march in a week or two to support scientific freedom. Trump does not determine scientific truth, peer review and the scientific method does.
