Not the author, but I’d say because public transit budgets are generally fixed amounts of money, so if you spend millions on a light rail line, you don’t have that money to spend on buses. I agree that a light rail network with feeder bus lines can work well. Boston’s “T” had done this in Cambridge - there’s an underground bus depot at the Harvard Square subway stop, where buses from all over the north side of the river converge so people can move to the train for the trip into downtown Boston.
