What are possible loopholes in the Lightning Network?

[adncoin]

BTC's Lightning Network is designed to free up Bitcoin’s on-chain congestion and improve its scalability but with recent news, it seems that the network capacity is declining. Why do you think so? What concerns should be addressed by the network?

it is not really declining, its growth just slowed down and the total capacity fluctuates as people go in an out of the channels. with recent price rise and the on chain fee increase less people are opening up channels so the capacity is not as big as before.
none of it has anything to do with "loopholes" in lightning network though!
