While "copyleft" is just a word like any other word, and subject to the same descriptivist drift as any other, in this case it is a specific word coined by a specific org, with a pretty specific definition. One that this license does not meet.
Frankly, copyleft is MORE permissive than generic bullshit weasely term "open source" (thanks to corp-friendly ESR). The fact they try to avoid using "open source" but willingly use the more "free as in freedom" word "copyleft" is a bit distressing.
I'm tired of this whole "shared source" movement, it's disingenuous, and ruins the spirit of actual open source (let alone "copyleft").
Boo on Winamp. Shame. I'm still using 5.666 until I die. I won't use their newer stuff, because it's clear they're not doing it with love but just trying to find another captive market of nostalgia nerds.
