Apparently the popularity of the Lightning Network has risen to the point where it is possible for an operator to earn thousands of dollars per month in routing fees. Imagine how much this could be when you're actively jamming the competition's channels. Not only can you capture their traffic, but it will also be possible to command a higher fee rate because senders probably still want those payments to go through.
