Like prioritizing a legitimate website over a scam website isn't punishing the scam website because of a controversial opinion or the search engine operator didn't like the content, it's because the website is objectively a scam, it's easy to objectively identify it as such, and everyone agrees it's one.
When it comes to Ukraine vs. Russia and propaganda, it is entirely impossible to have objectivity. As angry as this will make some people, opinions on the war in Ukraine are subjective. Russian outlets shouldn't be ranked lower than Ukrainian ones solely because a lot of people are on the side of Ukraine.
I'm sure some Russian outlets are spreading objective falsehoods, and some Ukrainian outlets are spreading objective falsehoods. These individual outlets should be punished in search rankings, but to classify all Russian outlets as spreading misinformation and all Ukrainian outlets as objective truth completely demolishes the objectivity a lot of people want their search engines to have.
It's a difficult topic, I feel like I talked in circles writing this comment.
