I appreciate that it can be confusing for users that patents can still apply to techniques where implementations exist that are both libre and gratis from a copyright perspective, but this has been an issue for Linux-adjacent software distribution for ages—like, see how Debian used to put certain stuff that was encumbered by patents in the US but not in other jurisdictions in special “non-US” repository sections, that sort of thing. It's not Black Magic's doing that the codec space is like this. I wish people wouldn't make so many mocking assumptions sometimes.
