I believe the error was in the AV1 license NOT having a "if you enforce patent-license-fees on this codec, THEN you can't use this codec" type of coercion..
( I may have got the logic wrong, but there's some kind of license that works that way, which other open codecs have used, apparently )
Just ignoring that predators exist .. provides NO protection from them.
You have to make your license-agreement break abusers, .. or you're just helping them.
