I'm not sure this is EU bashing, it could equally be Sweden bashing.

The article isn't, but many accounts now dish out anti-EU narratives in any topic remotely touching Europe.

A lot of it for sure is either direct propaganda, or internalized anti-EU sentiments after reading too much of that propaganda on other platforms.

Weak Europe is what both Russia and the current US administration are explicitly promoting, so it's not surprising to see an uptick of those comments. Most countries now have pro-Russian alt-right/left parties, and their supporters are very exposed to foreign state sponsored messaging.
