the fact that there are this many people having different interpretations shows that the license would need waaaaaay clearer wording to hold any sort of water.

this is why i hate licenses like WTFPL and its ilk, just saying "do whatever" cannot possibly be legally viable and thus using anything with such a license is impossible by anyone who cares about copyright law (such as say, companies).

If you want your creations to be free for all to use, just slap a fat CC0 on it.
