I don't recall any banks announcing that they were going to run Lightning nodes.  That would be a pretty major headline I'm pretty sure I would have noticed.  Like most people involved in Bitcoin, I'm not a fan of banks.  I'd be dubious of anything that resembled traditional finance and fractional reserve making their way into Bitcoin.  Thankfully, the closest thing we have to that are called Exchanges.  If only people directed their misplaced vitriol at those instead of attacking Lightning, which could well lead to completely decentralised exchange.  There are no banks in Lightning.
