Or did he? The Ukrainian government promotes radical nationalism because they see it as an ideological bulwark against Russian World or whatever you want to call it. The ideology that Ukrainians and Russians are single people divided by historical circumstances. There are many people that believe in this, including yours truly and the Ukrainian state views this as a threat to its sovereignty and in opposition to its Western backers.
And Poland can only suck a dick. Poland is a lackey of the collective West that uses Ukraine as a proxy to fight Russia. Poland has to suffer Ukraine’s apologetics for Nazi collaborators. All Polish politicians can do is to condemn Kiev and Zelensky. In reality, Poland is happier with UPA worshipping Ukraine than Ukraine, which celebrates victory in WWII. Victory in WWII meant domination of Eastern Europe by the USSR and its successor Russia is seen as a threat.
