I'm interested to know what is your definition of the Lightning Network being "centralized".
Because it's not managed by a single authoritarian or a central server.
Majority of users are using custodial lightning network wallets, and it's all being hosted on big hosting servers like amazon, g00gle, digital ocean, etc.
I have seen reports that 98% of Lightning Network users likely don't run their own node or manage their own channels.
This is not ''fud'', it's reality and common knowledge.
