It was sad to read the thread where Jarek Duda introduces himself to the WebM codec developers group and suggests using Asymmetric Numeral Systems for VP9 / AV1.

Then he notices patent applications about his algorithm and asks Google to help: "Maybe Google could help fighting with it?"

It seems that Google helped by patenting it themselves??? So sad.
