Wikipedia censors a lot of information. For politics, it’s not a reliable source of information.

We’ve already discussed the banning of Russian culture and it is confirmed.
The provision, which entered into force on January 16, is stipulated in article 25 of the law. It requires print media outlets registered in Ukraine to publish in Ukrainian. Publications in other languages must also be accompanied by a Ukrainian version, equivalent in content, volume, and method of printing. Additionally, places of distribution such as newsstands must have at least half their content in Ukrainian.

So, as is said, the law does not ban the use of Russian. It just states that Ukrainian must be used alongside it. Oh, the horror!
