Twitter never shut down Wikileaks or other things in the interest of national security that involved civilians and government officials alike. They have allowed journalists to leak other similar stories from hacks constantly. The Panama Papers, etc were all mostly civilians. Twitter never censored that, except in China at the behest of the CCP. Which comes to the original point. No politician or political arm should have the power or influence to take something down they find unfavorable. I prefer not to live in a CCP like state where the "party" gets an edit button on everyone's thoughts.
