- wireless is a broadcast medium and thus trivially eavesdroppable. To make it NOT eavesdroppable requires crypto. Crypto requires agreement between the AP and the client, and crypto steals bandwidth. This has to be unique for every client/AP pair. This is a huge bookkeeping exercise that a) will fail b) will cause regular issues and c) will cost a lot of money. Fibre does not require any such protection because it is not a broadcast medium.
Actually PON (passive optical network, the type of fibre install used for FTTP) IS a broadcast medium and also needs encryption to prevent eavesdropping.
