Banning state propaganda is great, but why limit that ban to Kremlin propaganda? US propaganda is just as, if not more, prevelent and toxic. The narrative surrounding the destruction of the Nord Stream is a good example:

American corporate media and government officials were calling for its destruction and outright threatening to blow it up for months prior to the actual attack. Immediately after its destruction, the corporate news outlets and government officials that had been calling for that very action acted as though they had never done so and presented a unified front that blamed Russia for the attack. Doing some critical thinking and realizing that Russia had neither the opportunity nor the motive to blow up their own pipeline is not Kremlin propaganda. Continuing that critical thinking and realizing that the US had both motive and opportunity, and was a likely culprit because they had repeatedly threatened to blow up the pipeline is not Kremlin propaganda. Shutting down all discussion critical of the US by dismissing it as Russian bots is US propaganda.
