I think you meant "Just because AVC is a standard doesn't mean it's not
proprietary".
^^^^
"Proprietary" means owned and controlled by one entity. Yes, AVC incorporates
patents owned by several companies. But nobody owns it, and anybody can
participate in its ecosystem.

Even by that unique definition, AVC is not proprietary since it can and is
(e.g. x264) implemented by the whole world without permission.
