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 -
https://github.com/cdecker/lseedA DNS seed for the Lightning Network
edit
to counter the fail of calling it Fud/conspiracy from trainwreck
Ok. How can this be abused ?
This is for convenience just like the bitcoin DNS seed. Every lightning node operator
will make sure its well connected to the rest of the network so this is a minor nuisance even if abused.
