And NATO or ukrainian propaganda?

Because that is also a thing, even though not as blatant.

The problem with banning information, is that it is easy to abuse this and it creates a martyr effect. I rather would like people be able to judge information by themself and not decide for them.

Not really. I preferred the approach of pre-Musk twitter that clearly labeled it as Russian state media. Also banning it had little effect. The war propaganda coming out of Russia was hilariously incompetent.

The real insidious anti-Ukrainian propaganda is coming from pro-Russian Westerners, pre-dominantly the American populist right.

If you think your citizens are vulnerable to being tricked by Russian propaganda, you have a much bigger problem than Russian propaganda.
