Previous president of Ukraine was a literal power hungry oligarch, who engaged in war, war mongering, censorship, propaganda, fake comments trolling bots, policy washing through his international friends, fake-fighting of corruption to gain power over judges, ordered raids on opposing media and industries, switched politics to right-wing to ride the propaganda machine he tried to create, etc. New one is a freedom of speech supporting businessmen, not an oligarch, who found himself fighting him and the whole establishment through utopian/dystopian political tv shows over the last five years. And newly elected parliament has plenty of people who have no ties to the establishment or fought the last president too, like the head of the most active organization fighting against internet censorship (pretty successfully) who joined the new president's party.
It doesn't work like that. They are their own people, not puppets as you try to imply. And it's not like oligarchs even have that much power to make someone into a puppet, they are not FSB.
i think that political regime in Ukraine is purely oligarch-based. Ukraine does not have strong traditional government institutions, instead the government is driven by current oligarch configuration. it used to be Yanukovich, then Poroh, now it is Benya (via his proxy Ze). just look at Groysman, the prime minister, as they say in Russian, he "changed his shoes while walking" and switched his allegiance from Poroh to Ze/Benya in no time. government in Ukraine is weak and servile. they have stronger civil society, but it shows in short outbursts, then oligarchs take over again.
