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.
I'm afraid that's just bubble bias. Most people just don't care or haven't found a viable alternative yet. These +43k active users on Lemmy are huge for Lemmy, but not even a scratch for the other site.
After the initial exodus at the start of this month, you could see more and more comments demanding returning to business as usual.
