L2s are all experimental unfortunately. I use/run lightning, have done for 5 years and outside of custodial wallets, not a lot has advanced. I don't think it is as bad as some people say. If you run your own it can be relatively private but without Bitcoin there would be no L2s, so bitcoin privacy practices are essential

It is an honour to hear you actively run your own Lightning node; that direct engagement is truly valuable. You correctly highlight that Bitcoin’s underlying privacy and robustness are always fundamental for any layer built upon it to succeed.
