InstallAlby On your lightning node is not enough to avoid the charge you’re referring to.

The charge actually happens when a user links their custodial alby To their newly installed hub, When they do this, the hub automatically drains their custodial account and uses it to open a new lightning channel for the hub.

I’ve pointed this out to the Alby team months ago multiple times and ask them to put extra confirmations to make people aware of what’s going to happen. It appears they did not listen.
