As someone who has run a lightning node for almost 2 years now, my opinion on average Bitcoiners running their own node has changed from "it's a great learning experience" to "it's a big time sink and a nontrivial risk and probably isn't worth the effort".

Lightning is centralizing! And I don't think that's a bad thing. It just makes more sense to have a handful of very large nodes that handle most transactions. It is, and will always be, permissionless and non-custodial at the protocol level. There's no barrier to entry if someone wants to start a routing node other than liquidity and good capital management.
