Zelensky's ban on pro-Russian media outlets
President Volodymyr Zelensky on February 2 enacted a package of sanctions put forward by the National Security and Defense Council, effectively blocking a number of media assets, including 112 Ukraine, ZIK, and NewsOne TV channels that had been multiple times accused of preaching pro-Russian rhetoric, formally owned by Taras Kozak – an MP and ally of Vladimir Putin's crony Viktor Medvedchuk.
Commenting on own move, President Zelensky said he strongly supports freedom of speech, but not "propaganda financed by the aggressor country."
SBU security service chief Ivan Bakanov said, "There is a big difference between freedom of speech and outright anti-Ukrainian rhetoric. Freedom of speech ends where signs appear of encroachment on territorial integrity and sovereignty of Ukraine."
U.S. diplomats in Ukraine have supported the move and called for joint efforts "to prevent disinformation from being deployed as a weapon in an information war against sovereign states."
Meanwhile, the European Union's External Service said it was "assessing the implications" of the ban on TV channels.
