Good, it is a start. And much better would be for those EU politicians, journalists and other people to move to Mastodon, Pixelfed, and similar independent platforms. That would make a much better example.
I can't understand why government offices for many countries are still on Twitter. At least Germany has their own mastodon service, but my home country Finland still uses Twitter.
I don't have a problem with public bodies being on Twitter, but they should definitely be on somewhere else too. They need to be where the people are, and people are going other places.
