Well, the guy in the video does not say, that LN nodes are like banks, but that they are owned by banks - which makes it a huge difference.
I didn't see this as BCH propaganda, because I also don't believe in BCH because for me the idea, that crypto has to work as a currency is flawed altogether. Crypto for me is an investment in a decentralized technology or business model - that's it. Which doesn't mean, that I am "right" or that anyone believing in it as a currency is "wrong" - it simply means, that I see Crypto as what it actually is at the moment (=no currency at all) and works as stocks do. That being said, I will have a look at your links now - thanks for bringing it up and your effort to shine another light onto BTC.
