Yep, everyone is competing to make a double-sided market which is very hard. I also get the sense that leasing liquidity has very weak demand. It seems to only makes sense for someone that predicts they'll receive many small payments over a period of time, payments they can't get by some cheaper (aka onchain) means, is willing to trust the channel leaser, and also can't provide the liquidity via submarine swaps for themselves. ie I think there's lots of desire on the part of bitcoin holders to make use of their bitcoin like this, ie supply, which is why I think we see so many of these markets with low demand, but it's also not heating up your bitcoin storage for 1% theoretical yield in a weak market.

Then again, I'm just guessing, and it can always just be too early.
