It doesn't matter what the philosophy is, it matters what the laws says and what it allows you to do. Many companies don't want you to resell their products on ebay (their philosophy). However, the first sale doctrine says something different (the law).
So while you may not like someone re-packaging and re-selling open source software, as long as they are following the license, there isn't much you can do about it.
Your main point is true, but I'd like to point out that copyright circumvents the first-sale doctrine. You're not allowed to copy and distribute works that you own, if you don't have a copyright license for the material.
