It's a trap
If we ditch our landlines, our cell phones will light up with robocalls because we wouldn't want to cause "hardship" to businesses trying to sell us something. I keep my landline to draw the traffic away from my wireless service. The ringer has been silenced and the calls go directly to voicemail... following a lengthy set of twisting options to leave a message (press '1' to leave a message) which confuse the robots.
I am a human being. My telephone is designed for human to human interaction. If you are not human, I do not want to communicate with you by telephone.
