They want you to upgrade because they want to ditch the copper. Once they pull the copper out they never have to replace it. Keep it for as long as you can. I regret switching over to fiber as I am back to a cable modem anyway(frontier is a terrible company worse than comcast which is why i am now back with them) and now I can not get any copper to my home.
you should set up a bbs on your telephone line. the bbs scene is making a comeback and while most of it is over telnet/ssh its fun to have an actual telephone line.
