This is a battle for future default image codec: open standard vs nearly proprietary controlled by a few corporations - https://en.wikipedia.org/wiki/Alliance_for_Open_Media : > The governing members of the Alliance for Open Media are Amazon, Apple, ARM, Cisco, Facebook, Google, Huawei, Intel, Microsoft, Mozilla, Netflix, Nvidia, Samsung Electronics and Tencent.

For example with defensive license termination: they can sue you, but if you try to sue them you have to rip off AVIF from all your products: https://aomedia.org/license/patent-license/

>Defensive Termination. If any Licensee, its Affiliates, or its agents initiates patent litigation or files, maintains, or voluntarily participates in a lawsuit against another entity or any person asserting that any Implementation infringes Necessary Claims, any patent licenses granted under this License directly to the Licensee are immediately terminated as of the date of the initiation of action unless 1) that suit was in response to a corresponding suit regarding an Implementation first brought against an initiating entity, or 2) that suit was brought to enforce the terms of this License (including intervention in a third-party action by a Licensee).

Defensive license termination is actually a good thing. It is how you can keep a codec royalty-free. Without defensive termination, it is way too easy in the current patent system for patent trolls to make bogus claims and bully companies into paying them royalties. JPEG XL also has defensive termination clauses, and so do the Apache 2.0 and GPL v3 FOSS licenses.

AOM has noble goals: royalty-free codecs for the web. JXL is also a royalty-free codec that is very well suited for the web (as well as many other use cases for still images). There is no reason why we can't just have both supported by browsers.
