Guifi has a connection to the local Internet Exchange in barcelona (catnix) which is managed by exo.cat (an association of people paying a bi-yearly fee to support the expansion of the guifi network) as well as other connections around barcelona and other cities / towns. A lot of people shared their internet bandwidth which here in Spain was not illegal or blocked by the ISPs if you where smart. There are also several small ISPs that have been created that sells internet and telephone services over the guifi network.
