Sorry for being unclear. What I meant is:
These actors play nice until they are too big to ignore [as a presence in the fediverse].
When they run the most and the biggest popular communities on their instances, do most of the development, offer the best tools and services in the fediverse, they have become too big to ignore.
If they then start playing dirty, it is too late to defederate them. They will play dirty. Let's not make ourselves dependent.
Interesting. I never heard of Evtopia, and I also did not understand Utopia as necessarily impossible. Could be possible or impossible, depends on context.
I also don't think being unreachable is necessarily a bad thing. Consider an 'Ideal'. Although some ideals may never be fully actualized, they are seen as something good and worth pursuing nevertheless.
But mostly, I don't think the opinions of proponents or opponents of this idea are swayed by wether we call it Utopia or Evtopia. If anything, using the more common term makes it more relatable.
