Thank you for this nice post !
Unfortunately this confirm that LN = centralization ! It's against Bitcoin's primary objective and personally i can't support this technology (In the current state and especially if nothing will be made to improve the idea more in decentralized way).
2 importants depreciated factors join the game: Middle man and Trust.
Of course there adventages using it like enjoying a micro transaction fees, save Blockchain transactions ... but what about security (Keeping things decentralized) ?
I am not the negative guy of the gang, it's great to offer solutions to improve bitcoin or blockchain technology ... but security first (Especially when people's money at stake).
