> it's "Russian propaganda" if it's anti-EU
No, it's propaganda if it's distorted or completely false.
For example, here you can find my article that is very critical of particular aspect of EU policy (electronic signature) https://sas-space.sas.ac.uk/5453/1/1920-2703-1-SM.pdf
Is it propaganda? No, because every single criticism is based on facts from EU legislation back then. This article was discussed at technical commissions in EU and nobody had any problems with it.
