> Hola works because it is a peer-to-peer network - you use the network and contribute to the network. To provide this service without charge to our community, Hola charges validated corporations for use of the network. For Hola users that do not want to be a peer in this network, we offer the Hola Premium service, which lets you only use the network, but not be a part of it

Seems quite knowing to me. That same FAQ page, which is very detailed, even provides an explanation of what permissions are used.
