I'm afraid this is not at all bullshit, even though I wish it was so.
While it is true that these opposing countries no doubt each have their own problems with (local/national) corruption and oligarchies, the ideologies that are currently being forced on them are very much the product of corruption and oligarchies on a much larger scale (just better hidden). In fact, none of these ideologies are what they claim to be.
This is all about powers who have essentially hijacked the EU project for their own greedy gains. This ideological criticism in reality just attempts to crush the (relatively amateurishly organized) local competition to their own hegemony. That isn't propaganda. It's an organization who cleverly knows how to abuse the general ignorance of most citizens regarding these countries and abusing it to frame reality into a conveniently useful picture/justification for their attempt to take (even more) control.
As much as there is all kind of things wrong with these opposing countries, of which there indeed is plenty, there is equally nothing good or lofty about what the EU is doing at the moment. As ironic as it might be, the local corruption and oligarchies in these countries may in fact only be child's play compared what has infested the EU.
The main difference probably being the success with which criminal elements within the EU have managed to hide their activities from the general population. Probably not in the least by "outsourcing" a lot of its business to either outside EU, or to local shady endeavors in these countries now criticized, where it's a lot easier to hide how profits are being made.
Of course, countries like Czechia, Hungary, Poland and a few more certainly should do more about their internal corruption. But what most people forget is that the current status quo to a large degree was build up and supported by powerful figures within the EU. Most of that because these corruptions at the fringes of the EU territory just so happened to be very convenient and profitable for the people who "accidentally" let all of this happen on their watch. Mind you, figures like Victor Orban became as powerful as they are now by gaming EU rules, with the full knowledge of those who made and governed those rules!
