> It's a lot harder for people to spread misinformation online in a country like Estonia without speaking Estonian and keeping up with Estonian affairs. I think even corruption would be harder to swing against officials in a small European state compared to the EU, because things are less likely to be lost in endless European bureaucracy.

What does spreading misinformation have to do with corrupting the government? If you want to spread misinformation in the EU, you also must target every individual country. There's no EU-wide propaganda channel.
