I'm very aware of the corruption in the EU, corruption will always happen because greed will always happen, the questions are: what is the level and degree of said corruption? What do institutions do to fight it?
Living in this black-and-white world where you expect absolutely no corruption is not helpful, von der Leyen has plenty to answer on the Pfizer case and as far as I know the case is still being looked upon so institutions are working, they might not be as fast as we would like to see a conclusion but that's how it works as of now.
I'd suggest you to play less into the shitstorming, it just creates even poorer discourse on the internet, the effects of such poor discourse can be seen on the political environment of the USA at the moment. I believe we can all agree that's not a path we would like to go to.
A major problem in EU is that it is at least in practice very opaque. EU politics are not followed by the media or the citizens, and it is surrounded by a gigantic lobbying machine, and run by democratically unaccountable officials.
E.g. US corruption is at least mostly in plain sight, with EU who knows what's going on.
Will there be issues? Of course, whenever money is involved there are issues but as usual: level and degree matter. It's not binary black-and-white.
