I have my phone number and mailing address on my Facebook, set to friends only. Why not? When I grew up, we had a phone book listing everyone’s name and address and phone number so you could find them to contact. I consider all of this essentially public information and would rather make it easier for people I know to contact me. If it gets lost in a breach, whatever. I already get plenty of junk mail because I give to charities and they sell my address.
