Thank you for your attempt to open a discussion. I personally think that the LN approach is the one Signal should have taken, and would love to see it implemented. Fortunately Keet for mobile is coming, and once it does, I will encourage everyone I know to switch over from Signal. I won’t be using single anymore.
Unfortunately it seems people in that community thread have some cringe-worthy misconceptions of environmental impact of Bitcoin, they really should educate themselves on the content and crux of the matter.
