MIT researcher Thaddeus Driya, co-author of Lightning Network whitepaper and former technical Director of Lightning Labs, believes that the network will avoid corporate centralization in General because of its design, which does not require expensive and does not require specialized equipment 
Co-Author of Lightning Network, kind of a conflict of interest , don't you think for an impartial opinion.
LN Hubs will be required at the least to report as a money transmitter at worst as a banking institution.
The expenses for these will make it so very few actually run a hub once enforcement of the AML/KYC regulations begin.
The LN hubs fees are also variable , it is funny no one thinks that their fees price can't also skyrocket.
LN Hubs require constant internet access to avoid funds being stolen, a simple ddos attack at the right time could allow LN funds to be stolen.
There is talk of a WatchTower system to help prevent that, but it is also going to charge additional fees if it ever gets working well.
