Some say that the Lightning Network is centralized, but from my point of view, it's still a decentralized solution to scale Bitcoin as anyone would be able to run a Lightning node at will. The huge advantages that it provides for Bitcoin such as dirt-cheap fees, and instant transactions would be too hard to ignore to implement in the future.
However, if the Lightning Network turns out to become a centralized solution for Bitcoin (like many claims it will), then it would be doomed as only those with a lot of wealth and power would be able to participate in this ecosystem.
What are your thoughts about this? Is Lightning really centralized? Or Decentralized?

Lightning Network will be centralized.
Whether or not that dooms it has yet to be seem , but it will be no different than a Centralized Banking System.
As far a LN fees being cheap, it has not even begun to be used, so the promise of cheap fees may be exaggerated and proved to be false as usage increases.
LN is also a variable fee structure as such as it use increases so too will their fees.

Bitcoin core transaction fees were cheap , but they increased in time , odds are so will LN's fees.
