Cool, finally some agreement here! That's what they are, copy protected if the content creator wants them to be.

"and not be tied into our versions of Vue so they will only work with one version and if upgrade have to download again to get a newer version so it will work."

Well that's cool too! They will work with upgrades without having to download again, so where's the problem?
