Taproot should lead to a massive improvement in the privacy of the lightning network.

Stop shilling nonsense. Taproot today doesn't do shit for privacy of average users, but BTC is today shilling that falsehood as hard as Monero claims to be king and sole way of doing any modicum of privacy. And lightning is riddled with flaws. Liquid is supposedly better, dyor. If BTC users want privacy, they need to look at joinmarket, and to import things like cashfusion, look at wasabi/samourai, and a bunch of other methods. And to get off their ass and build cross-layer-0 DEX and anonymous p2p exchanges. Bitcoin "core / foundation" or whatever else they call their sold out selves haven't and thus are not going to be doing that, thus you have to.

flaws in the existing lightning network were the result of enemy action.
