I used to buy this, but I disagree.

If you could say your school friends were "real friends", you can say your work friends are real friends. Modulo some child-like naivety, you were only friends with your schoolmates because you had to be at school with them. Hell, say you're homeschooled, and you're friends with kids in your neighborhood; you're only friends with them because you have to live around them. You can always make this argument for all except purely Internet friends you plucked from the æther of some Discord server.

No-strings-attached friends are different from school/geographic/work friends, in terms of quality of life threat and the social strategy that should govern your interactions, but I don't think you can't say they're all friends.
