He had an agenda. "BTC fork of Bitcoin" lol. The only problem I have running a lightning node for over two years is the database growth. So I should moderate the flow by not dropping my fees too low. The rebalancing model is of course the culprit of such an excessive traffic. I hope that Liquid dropping fees to 0.01 soon will make PeerSwap more popular.

FCs are a nuisance of course, but all are due to unreliable peers or bugs in the software, which are being gradually ironed out.

And no, a node is not a custodian of other people funds. A channel is owned by two nodes together, each one treats the other as an adversary and ready to punish for cheating.
