The F-35 are not necessary for Poland at all as these fighters are not designed for border states, which airbases can be destroyed within several minutes. Currently, no one threatens to Poland – it means that the F-35 purchase is realized under pressure from the Americans, without any trade negotiations.
Poland does not care about the peace in Eastern Ukraine, or in the East in general, nor about the well-being of the Ukrainians. The Polish politicians, thinking in the anti-Russian categories, perceive Ukraine as an important issue only if it harms Russia. Otherwise, if Ukraine stops harming Russia, the Polish politicians and publicists lose their interest in this country.
This message is a pro-Kremlin narrative on the “Russophobic elites”, which promote their anti-Russian policies with all available tools. In this case, the Polish elite allegedly uses the ongoing conflict between Russia and Ukraine in order to weaken Russia and promote anti-Russian policies. See other examples of this message claiming that the elites in Europe are Russophobic, that anything that's bad for Russia is good for Polish elites and that Washington has designed a plan to rob Europe.
The Polish government has repeatedly shown its full support to solving the Russia-Ukraine conflict and the complete restoration of territorial integrity of Ukraine. See other examples of disinformation on the Polish-Ukrainian relations claiming Polish policy towards Ukraine is shaped by the Americans, Ukrainian arms flood into Poland and that Poland wants to dismember Ukraine.
