If you federate with something too massive though it has undue weight on the entire system. It is likely to be Embrace, Extend, Extinguish again, and it's reasonable to want to avoid that.

For people who don't remember, the pattern would be something like:

1. Federate and use the existing ecosystem to help you grow and to grow mutually (Embrace)
2. Add new features that only work locally, drawing users away from other instances to your own (Extend)
3. Defederate - the remainder is left with a fraction of the users since many moved away, so the users on the local instance don't care. (Extinguish)

It depends whether 2 actually succeeds at pulling users in. Arguably most people already on the Fediverse are unlikely to jump ship to Facebook, but you have to consider what happens in a few years if it's grown, but Facebook is a huge name which makes people less likely to join other instances.
