Yup. Muscles PULL, not push. You work your lats by doing rows, seated rows, pull ups, chin ups and things of that nature. Push-ups are the exact opposite motion, and they don't do shit for your lats.
Just so we're on the same page here, and I'm not trying to be a know-it-all, but I'm gonna throw this up here..
Steve...been lifting for a solid 10 years, you're right. The primary use is pushing for chest/tris and pulling for back and bis. Secondary is stabilizers. Yes you will get development of your lats* and back from doing pushups. Try to do pushups with a loose back, you can't. You'll literally collapse.
You just need to break it. After hours and hours of repeated punishment, it just sort of gives up and doesn't care anymore. You know that dead look in a stripper's eyes when you're getting a lap dance? My taint has that.

You work your chest when you do pull downs too.
No, EVERY muscle can only pull... Your chest PULLS your upper arm bones in (and thus, raises you off the ground) when you do push-ups. Your triceps PULL your upper and lower arm bones such that they straighten relative to each other, which raises you off the ground when you do push-ups... Your lats PULL your upper arm down towards your side, which is what you resist with body weight when you do a wide-grip pull-up, or with weights during seated rows.
...I have no idea what you even mean by "pushups with a loose back", since those muscles aren't used in that exercise [save for minimal amounts for stabilization]. Your abdominal muscles are what are keeping you from collapsing onto your knees or the ground when you do push-ups.
I've also been lifting for around 10 years, broheim.
*by "pull" I mean that the power in a muscle comes when it contracts.
