If I send someone an a message via snail mail, the USPS does not charge the recipient the cost of delivering the message. If the message is sent postage due the recipient does not have to accept it.
USPS had "postage due" for longer than it's been gone. You could put a message in the address like ARS for "arrived home safely" and send it PD. The recipient checks the address and then refuses the letter. After the letter carrier makes a couple of unsuccessful attempts that is.
Those reasones and a dozen others made it a money loser. People didn't care enough to pay what it cost.
People are addicted to SMS and addicts will pay whatever it takes.
