"Blockstream is a company founded in 2014 by Adam Back, who currently employs most bitcoin core developers."
"Wait? Isn’t the lightning network decentralized?
Because of how the lightning network, nodes and payment channels work — there is an incentive to use the fastest and cheapest hub with the most connections to other nodes. Merchants will incentivize customers to use “super nodes”. These “super nodes” may start small like a “Sydney local transaction node”.
So these “super nodes” could become very large, and who knows what will happen with that. Will they be controlled by the government? Could a fractional reserve banking arise again? Many bitcoin core support argue that it’s very unlikely — but it is a possibility.
Asking these questions about the lightning network on bitcoin communities leads to almost NO responses, because nobody knows how exactly it’s going to play out. Not even the Lightning Labs CEO. It’s still a work in progess."

Most likely these "super nodes" as you speak of will most likely be ran my mining pools as they usually have a huge amount of BTC and will allow them to collect fees even without having to find and solve blocks
