"Blockstream is a company founded in 2014 by Adam Back,
who currently employs most bitcoin core developers."
"Wait? Isnt 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 its 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 its going to play out. Not even the Lightning Labs CEO. Its still a work in progess."
