Yeah, that fee was for opening a lightning channel. With Zeus, you're running your own lightning node, and are fully self-custodial. It's a good choice for some, but if you're only using lightning for zaps, it may not be financially justifiable to commit to the fees associated with running a full node.
Until I can connect to channel it order to open one, Zeus will have to do. I can't get Alby to work and I can't connect to any of the channels through Thunderhub or RideTheLightning. So right now Zeus is it.
