The author doesn't quite get it. Nonwithstanding the fact that physical infrastructure is never free (his fido example is a case in point: phone lines), once something turns big corporations will enter the game, and then even freifunk-like architecture would suddenly be corporate-owned, as their nodes outnumber private ones.
