Only personal use is protected for non-members. So it seems that commercial use of WebM, or any distribution of WebM, requires joining the CCL.

Is this some kind of "patent-left" (as in "copyleft"), where you get protection if you in turn promise non-aggression? Yet it seems only to apply to 3rd party patents as Google has already freely promised the VP8 patents as far as I'm aware.

I'm not sure I really understand the point. The only obvious benefit is that companies can legally bind themselves to prevent future use of their patents against WebM if they go bust or get taken over.

It's about 3rd party patents possibly applying to WebM. If they apply, they are not part of the WebM patent grant, and thus not permitted for commercial use, or distribution to non-members.
