The 1% was rhetorical but it is not far off. Even if 5% are sovereign LN users, not all of them are adhering to best LN privacy practices.

Count custodial LN wallet downloads. Count non-custodial wallet downloads that require LSPs to use. Now compare them vs non-custodial wallets where you can optionally use your own LN node or must use your own LN node. Very easy for you to do, but I can go do it right now and give you up-to-date stats if you want.

Look no further than everyone using custodial addresses on Nostr to give you another broad view of custodial LN adoption 💜
