So your argument is that blockstream will have the biggest hub. Can you tell us why you think so ?
What does blockstream have that nobody else running a hub has ?
the DNS seed that controls the routing.... obviously
the DNS seed is used for jumpstarting bitcoin nodes not for lightning
thats a bitcoin DNS seed
LN has its own DNS seed..
remember
rusty russel of LN is a blockstream employee
remember
Cdecker is LN is a blockstream employee -
