Well, this on is fibre. It is Movistar in Spain. And they are starting 
to "fine" people that use their own optical router. The EU can be 
fucked. Not fine, they simply cancel service.

     *Telefónica has issued an ultimatum to those connecting 
non-official equipment to its fibre network. They must either return 
their router or risk losing their service.*

     The freedom to connect one’s own equipment directly to Movistar’s 
fibre network is coming to an end. Movistar is sending a warning to 
users who do not use its official equipment, notifying them of a drastic 
measure: they will lose their connection if they do not return the 
original equipment.
