Actually, no. By content, I am referring to all content, including artwork, and it's certainly not a non-issue. There are many uses for WebGL besides games. Imagine a small company that wants to put together a snazzy 3d website and use clip art (3d models) that they purchase online. As I implied in one of my posts, a lot of the companies that supply 3d clip art stipulate that you have to take steps to prevent it from getting stolen and used elsewhere. I wasn't sure that obfuscation is enough, but after a bit of research I do believe it will be enough to discourage all but the most determined of hackers.
