“Channel liquidity and offline receives, in my opinion, are the two most obvious reasons why self-custodial lightning is not popular.
When most users hear about any of these, they just think “screw that” and move to a custodial wallet because it is so much easier. If these were our only two problems, I think self-custodial lightning would be fine.
It may never be the predominant way people use lightning, but we could get the UX good enough that we have a significant portion of people using lightning in a sovereign way. However, there are more problems under the surface.”~ BenTheCarmen
