@petertodd you're absolutely right, but in this context, I think intent matters.

The intent of their omissions (what you call a "lie") is to abstract. I don't think it's malicious intent to deceive or steal.

They are trying to abstract away on-chain and LN fees.

It's a hard problem.

If/when solved, the UX will/could be better than any other wallet.

They are obviously trying.
