Anything I've ever read or listened to go over basics of privacy on Lightning always recommends CJing before opening channels. And presumably if you're running your own LN node, the most private way to use Lightning, you would be doing that.

I feel like all this is moot though because thats not how the vast majority use it they're all on custodians like WoS that see everything.

The view key thing already assumes you're protecting those keys the same way you would protect your xpubs or private keys for Bitcoin/Lightning. Unless you think that applies to those as well for any wallet and crypto?

What popular wallets are leaking view keys?

The most popular wallets are all non-custodial and your wallet syncs the chain (Cake, Monerujo, Stack, Feather, CLI/GUI, etc)

Even if using someone elses node they can't see your view keys so no clue what you're talking about
