It’s run by a travel agency called Gondwana Collection. The watering hole is at the Namib Desert Lodge [1] so it’s not really remote, they just use whatever internet provides wifi for guests. The watering hole is set up to attract wild animals for the tourists to see so that’s often who runs them. The livestream is a cheap way for them to attract guests.
