there are many ways to do offchain scaling and payment channels are one of the worst ways. they are a very specific type of plumbing that only makes sense in specific situations, that coincidentally are almost always involving some kind of custodian

I think that makes sense if you consider them as essential but a payment channel on monero is at worse just a communication channel between 2 people, we get the bad taste from Bitcoin because it's seen as an essential scaling or payments solution and you have to get on it even inside a custodian, but XMR on-chain works just fine so no one would ever get pushed onto using solely payment channel networks for payments
