Don't be (it will not help you and it won't change a thing). Not forgetting that they're free to do whatever they want. No one is right or wrong, it's just... not ideal as it is ;)

Also, seeing how this is becoming kinda trendy topic relayed outside Lemmy I would not be surprised to see even more appearing. Say 'use-european' 'Support-european' 'made-in-Europe' (this one has my preference :p) and their obvious mirrors 'made-in-the-EU', 'support-the-EU', and so on.

I don't know about the other users but I can't be bothered with too many similar communities (2 is really a maximum as far as I'm concerned, after that it's just a mess that requires way too much time/energy from me to get anything out of it). So, I will ignore trends and focus on those communities whose moderation/participation I appreciate the most ;)
