Lightning network is a 3rd party offchain payment system
Would you care to name this supposed third party?
LOL, LN Hub operators.
Serious how did you not know that?
Guess it won't be apparent to you even when the LN Hub is Named Bank of America.
What can a "Bank of America" hub exactly do to Bitcoin if they become a Lightning Hub? Nothing. They can also do nothing on the Lightning Network itself because Bitcoins are locked in a multisig address when opening a channel. What it can do is build on top of Lightning and do anything they like but only from within their service.
Have the Funds to be a Centralized Hub that has the majority of channels to it directly , and refuse to open channels with hubs they or government policy disapproves of.
Therefore starving non-banking hubs of funds until they run them out of business and can have their own banking monopoly like with fiat.
Guess it is not apparent to you either.
FYI:
Or just slip a few bucks to a few politicians to pass a law requiring all LN Hubs to require a Banking License and follow all KYC/AML laws.
