Fuck, misclicked downvote (wanted to upvote). Really great how HN does not allow changing votes at least once. Sorry for that, but yeah good point.
Nowadays one or a few phone numbers are unique to you, which makes it linkable to other things. Linkability is something that breaks privacy, so if you don't want your full name to be known somewhere, it is important to be able to keep things separate. When your phone number goes public (e.g. resumé and snapchat), that anonymity is broken.
