It's also notable how many journalists (and even news outlets; the Irish paper of record just created an account, say) are suddenly using Mastodon. Realistically, the target audience of EU twitter feeds is mostly journalists; very few normal people will follow any sort of government twitter feed, but journalists will. Government bodies tend to use Twitter as a sort of low latency press release mechanism, and Mastodon will do fine for that, should there be problems with Twitter.
